grog6, the lastposter link code works like a charm. Thanks.
bitg is right about the Top Thread Starter bug. If you have a forum with only one thread in it, it will also give the error where it will show 100 % but no Top Thread Starter username. If you also have a forum where every thread is started by a different user, it will not show the username, because it doesn't know which one to pick. You must have threads started by the same username for it to show the name. I hope that makes sense.
Amy, is there a way to fix the Average rating like you posted? It is still showing in one of my forums as a thread rating of 4 stars for an average and there are no thread ratings whatsoever in that forum.
