One thing I'd like to see on IP board is the ability to set the user registration usernames to a-z and 0-9 and then be able to use special characters in display name change, i think that would be quite nice personally. You could always preserve the original username in the url but change the username in threads and topics to the display name to get around any complications.

Me too.. at least normal ones like [] and . so that gaming clans can wear their tags.

I would even like to know how to get that change now. :)
