i have been having the same problem, try pm'ing a mod for the real answer. think i figured it out, could be ordered in most recent threads you've posted in. So its not about new posts in threads youve EVER posted in that are closer to the top, but now its about threads that have the most relevance. I like it, if you've posted a year ago in "seen from your jeep", "pics of your front end", most useless thread ever" etc etc etc then they will always be at the top which is kind of annoying. Whereas if you posted in a thread last night then in the morning if there is a response it will be at the top.
