@Edme Achillian, please avoid posting right after you've posted in the same thread (please give another person a chance to post before you do again). This is usually known as "double posting" or "multiple posting" on the HIO site.

If you need to say something more after you've posted but no one else has, you can make use of the edit button and add the new message in the same post. The edit button is the one looks like a pencil on the top right of your post.

As Maria said. Many new players make the same mistake, so it's no biggie. It's more important to learn from the mistake than to worry over what was accidentally done.
