It allowed me to change my username when I was signing up. Whoops, I thought it did. It had my name in a text box, I changed it, but it reverted to my "real" name". Hmm.
OK I see what happened, it created this account, using Face-schnook, but I continued on and made ANOTHER account using what I thought was my username for this one. Just sent a note
thru the "change username" post.
