“Glad you got it working but I really dislike “display names” and I think it’s the worst concept in WordPress. Very bad idea to allow users to spoof other names. Even the “impostercide” plugin doesn’t solve all the issues. No other blog/forum system has such a quirky concept.”

I think the same. In a forum it doesn’t make much sense. What if i want to send a private message to a user ? If he changes his display name and avatar it could be very hard to find who he really is. It shouldn’t be allowed in a forum with a lot of users, it could get extremely chaotic.
