Well, it was two days of notifications every time someone posts in the thread, and the 'ESB and ROTJ Wishlist', 'Adywan's Episove V' and 'Prequel Radical Redux whatever' threads generate a massive amount of responses. It happens every time Igo away for a day, too.
If it was the old days of 2 MB storage on Hotmail, I could never do it. I'd have to switch it so it only shows the oldest reply.
