Hmmm, it would certainly be very helpful to be able to search all of the IPs of a certain thread, forum, or the entire UBB (albiet rather time consuming). I was thinking something along the lines of the
A, moderator/administrator enters the IP number to search for (with wildcards (*)), the topic/forum to search in, and the UBB displays all users who have used this IP. The second option,
B, would be the moderator/administrator enters the username to search for, the topic/forum to search in, and the UBB displays all IPs for that user.
Hopefully someone has/can create something along these lines.

Thanks,
