The thing I miss about the old one was that you saw 30 threads with "latest replies", but it was extremely annoying that every day at some point some threads just disappeared from there and I'd still miss them (I still never understood the reason).
That doesn't happen here, but something like you have on most forums ("My active threads/topic") would be useful, getting a list of the threads in which you posted.
Also it's sometimes a little annoying that new posts are not marked as new posts, so when there are like 20-30 new posts in a thread, you don't know exactly where the first unread post is.
