1. The "desired username" field will be your login, and therefore is case-sensitive. Make sure you enter it EXACTLY as you would like it to be displayed on the board.

2. The email given here will be used to send a welcome message with a temporary password when your account is created, so please make sure to use a VALID address--if I can't get your password to you, you won't be able to log in. (And don't forget to check your junk folder for that welcome message, by the by, especially if you're using a Yahoo address--I've had problems in the past with auto-notifications from the board getting mistakenly dumped as spam.)
