I like being able to see who the last user was that posted in all threads when looking at the thread list. Since I switch between computers frequently, the cookies thing doesn't always work for me. Great example at http://forums.asp.net
This weekend I'll update the view who provides the thread info and see where I can squash it in. The last posts by user was planned to be added last weekend but I ran out of time. I'll try to squeeze that in too.
Not that it's up to a vote or anything.
