Whoops, posted in wrong thread.
The five year old posts are fixed, thanks Nik! Is there any way the Active Topics page could move to something similar to the old system (before Drupal). Rather than simply being a list of all threads sorted by time, it only showed the threads that had been posted on since you were last on the forum. I think it kept a track of the last time you visited, and cut any posts before that off the list. It also had options to only show threads that had been active in the last 15 mins, 30 mins, 1 hr, 2 hrs 6 hrs etc. If this is too much work then don't worry about it, what we have now works great. It would just be a little bit easier to see which threads need to be read.
