Mordrick,
I've had really bad trouble with this - it's not just flood control either. I hit 'reply' button, and the thing times out before processing my reply. I just had 3 attempts at posting a thread in the BGII forum before it let me. It seems to get so far then just stop.
I don't think it can be a problem with the Board though, if other people are OK. Must be something external to it.
