thats a hack attempt and can be very serious... you need to address the issue and change passwords for Administrator..
also i'd really change the login name for all admins to NOT be same as display name..
that's my #1 rule for all admins..
look @ your ubb admin log for suspicious activity..
Dumb question, but is it possible to change one's username? Having had the same username across several sites for over a decade now, I'd hate to change my display name, and I would be the other admins will object as well...
