Please take the time to get your names correct in the fields listed.
Name = display name. This is what people see you logged in as, and is the name on your forum posts.
Username = login name. This is what you use to log in. For safety it is sometimes best to make this different than your display name. (Note: The forum software looks up profiles by username, so it looks like usernames can't be hidden.)
If you mess up, just send me a message and I'll fix it for you. I know, the little icons on the registration form have the indicators backwards for these two fields.
