when I try to register my username (itzike) i'm getting:
"Cannot create account: the requested username is already taken in the unified login system"

when i try login with this username, or "forget the password" option i'm getting:
"There is no user by the name "Itzike". User names are case sensitive. Check your spelling, or create a new account."
