Thanks for letting me know. It's likely a software issue, a glitch in IP.Board itself. I let the tech guys know and they are looking into a fix if possible. Until then see if Tolak's clever little fix does the trick.
a hack? really?
Depends how many alterations have been made to the code to get the forum operating in its current state. Upgrades can break stuff, I've learnt the hard way with vBulletin
I'll put money on it not actually being a forum software issue, maybe ;p
