LOL.
Well, I just wondered if there was a sort or a query on a field that hasn't normaly an index on it. It doesn't seeme to be the problem if I understand you correct.
I'm afraid it's not my host. We have quit a bit of bandwith and the stupid thing is that I found another board, hosted on the exact same server, that has no performance problem at all (also uses this hack on my recommendation).
Our board has a bit more then 1000 members and the other has about 350 members. Maybe that's the difference.
Don't know yet and it's not such a problem that i'll uninstall or something like that. Like the hack too much
