Spent much of the night wrestling with the message board script on the NZDWFC site as well. It used to store each message in a seperate file, which is fine for small message boards, but not when you have 2000 messages. So now it stores the messages in monthly digests, which are a bit easier to work with.
My thanks to Nathan and
theta_g and the rest of the people in #DrWhoChat who put up with my bitching while I was trying to debug it.
