I have been on this forum for quite a while, and I have to admit it is one of the best I have ever come across. You moderators (specially chinaman) do a great job of making sure that things run smoothly here. (No I'm not buttering up)
Having said this, I would like to see three new features here:
1) My posts - This way I can see all the threads that I have replied to (or created). Being able to sort them by date or number of replies would be nice too.
2) Bookmark - This way I can bookmark the threads that interest me, and follow them.
3) Ignore - It'd be nice if we have the option to ignore posts from one certain user. I really missed this option while nishy ran amok
