When you first click "My Profile", just put your name in without a password to start out.
Then after you put the profile info in (can be as little as just the name "Charlie", then put a password where it says to. But, where it says "New Password" leave that blank. That is there for users who already have a profile and want to change their password.
Once you get a profile set up, let me know so I can set it to instanly post your messages.
I'm sorry about all the confusion.
