I really don't know where to post this so, sorry...
I'm a member of a Infopop board here:
http://www.3dnews.com/cgi-bin/Ultimatebb.cgi There is a problem where signatures are enabled in the board, they can be used, and the include signature box is automatically checked each time you post, but you can't change the signatures at all in your profile or anywhere.
I don't know how eager the adminstrators are to fix it, but I'm wondering if there is an easy fix to this?
