How often can I swap accounts?
You must wait until six months after the creation of your iNPC, as well as six months after your iNPC last transferred schools, if they have transferred before, to swap accounts. You are limited to three account swaps over the course of your characters' school career. This is separate from the three iNPC school swaps you also get, so if you want to swap accounts three times and transfer your iNPC to different international schools three times, you are welcome to as long as you wait six months between each.

Are there any other restrictions to when I can apply for a swap?
Yes. You cannot transfer when either of your characters is participating in an official sport event for their school, and you will need to wait until after the sport event has concluded. For example, if your PC is on a House broom racing team and you apply to swap accounts during the spring races, then you would need to wait until the race has fully concluded to transfer, and your application would be closed until then.

I want both of my students to go to the same school! Can this be done?
No. You must have a PC account (that goes to Hogwarts) and an iNPC account (that goes to an international school). You cannot have two accounts that go to Hogwarts, two accounts that go to the same international school (i.e. two students at Tenūsa), or two accounts that go to different international schools (i.e. one at Koldovstoretz and one at Durmstrang). One account must attend Hogwarts (this will be known as your PC account) and the other must attend an international school (this will be down as your iNPC account). When one account transfers in this manner, the other will swap out at the same time so that you never have two of the same kind of account.

What if I don't want to have my character move to [x country], but I want to have them move to [x school]?
The schools will not be changing their requirements to cater to you. If you want to attend Mahoutokouro, you must live in Japan. If you want to attend Castelobruxo, you must live in Central/South America (or North America/the Caribbean, by application only). You cannot live in the UK and attend Uagadou, for example; what school you attend is based on where you live, so if you do not want to change your student's residence, you cannot change their school. You must have your student move in order to state that they have transferred.

Can I bring my PC's pet with them if I transfer my old PC to an iNPC school?
Yes. Now that iNPCs have their own sub-accounts, they are able to have pets just like PC accounts, so your current PC will not have to lose their pet if they swap to being your iNPC at an international school. This is an automatic process, so you do not have to do anything extra for it.

Can I undo the transfer if I change my mind?
No. Once approved, you'll need to wait six months if you wish to swap your accounts back.

Can I immediately swap my old PC/new iNPC to a different international school if I change my mind?
No. Once approved, you'll need to wait six months if you wish to start another transfer for your new iNPC to attend a different wizarding school.

If I swap my iNPC to being my PC and bring them to Hogwarts, can I change what House they were originally sorted into on their sub-account?
No. Whatever House your iNPC was Sorted into upon creation of the sub-account is the House they will be Sorted into upon their transfer to Hogwarts. If you are unhappy with this House, either A) don't swap them to Hogwarts or B) roleplay their disappointment at not being in the House they wanted. You cannot switch Houses.

How did my old iNPC get to Hogwarts and get Sorted into a Hogwarts house if they didn't transfer in September?
If your old iNPC/new PC transferred over the summer (July-August) and would start school on Sep. 1 with the rest of the population, you are free to post in the year's Sorting thread and state that they rode the Hogwarts Express and were Sorted in front of the whole school with the new first-years. However, if your old iNPC/new PC transferred at any other point during the school year (Sep 2 through the end of June), your student would have arrived in Hogsmeade on the Mystic Pullman, where a staff member would have been waiting to pick them up and escort the student to the headmaster's office for a private Sorting. Afterwards, the student would have been taken to their new common room. This does not mean you can godmod Lear, however - if you would like to write your iNPC being sorted and mention him or any other staff member, you must reach out for permission.

If I swap my iNPC to being my PC and bring them to Hogwarts, can I automatically land my same spot on the sports team in my new House as the spot I had back in the iNPC school previously? For instance, I was a first-string Chaser back at [x school], can I be a first-string Chaser for [x House] now?
No, unless there is a spot open. The waitlists for sports will remain first-come, first-served at Hogwarts and at iNPC schools. When you transfer from an iNPC school to Hogwarts, you will have to manually go to your new House forum and sign up for whatever sport spot you want, whereupon you will be added to the waitlist and have to wait your turn. If there is a spot open, though, sure, you can go sign up immediately and be added, but it's still your responsibility to sign up for it. When you transfer from Hogwarts to an iNPC school, however, put your desired sport spot in the form and you will be put in the sport if there is a spot open (and, if not, you will be added to the waitlist; see below).

Can both of my characters keep their sports spots when they transfer to the new schools?
Your new PC (transferring TO Hogwarts) cannot. You have to go manually sign up to your House’s waitlist for whatever sport you would like them to play; we will not auto-add you to the House waitlist. However, your new iNPC (transferring AWAY from Hogwarts TO an international school) can be auto-added to a school’s team (or waitlist if the desired spot is not open) as long as you specify in the form above what spot you want them to take. TLDR: new PC no, new iNPC yes if there is a spot open.

If I transfer my PC to being my iNPC and send them to an international school, can I automatically land my same spot on the sports team in my new school as the spot I had back at Hogwarts previously? For instance, I was a first-string Chaser back at Hogwarts, can I be a first-string Chaser for [x school] now?
Yes, as long as there is a spot open. The waitlists for sports will remain first-come, first-served at Hogwarts and at iNPC schools. When you transfer from Hogwarts to an iNPC school, you put your desired sport & position in the transfer form. If there is a spot open, you will be added to the iNPC school sport's roster immediately upon your transfer being approved. The process is only immediate for the Hogwarts->international pipeline; when transferring from an international->Hogwarts, you have to manually sign up for a sport waitlist yourself (see above question).

How does this work with me being in the Index/being on an iNPC school roster?
When your swap is approved, your old PC (aka your new iNPC) will automatically be removed from the Official Index and added to the iNPC school roster for your new international school. Your old iNPC (aka your new PC) will also be automatically removed from your old international school roster. However, the new PC will not be added to the Official Index automatically; this is the only bit of work you have to do yourself (other than applying to a Hogwarts sport, if desired; see above for that process). To be added to the Official Index as your new PC, you must apply in the Index Re-Application thread by yourself and link the approved swap post in your Index application; only then will your new PC be added to the Official Index.

What do I have to do now?
Your next step, once you have been approved to swap PC/iNPCs, is simply to update your PC and iNPC to reflect their new schools (e.g. in their encyclopedia). Then you will need to go to the Index Re-Application link here and apply to have your PC be re-indexed; make sure you link to your approved swap post in your Re-Indexing application. Afterwards, you are free to RP your new PC and new iNPC as you choose!
