Ooh, I just discovered something! (I'm sure all of you knew this already.)
When you're looking at a list of threads, either in New Posts or one of the Forums, if you click the number of Replies to a thread you get a popup which shows who posted and how many times.
Here are the Sooooo thread numbers, though I believe it's for this second version of the thread only. I'm surprised how high I am on this list as I thought I barely ever get involved in the thread. Kevy crushed everyone, though the gap between GD and Alex is pretty major.
