"active forums" are where it's at! lol. But when I'm bored I'll go through some of the old posts in sections that interest me. The "Racing Forum" used to be the one that I always skimmed through. Otherwise, I try to keep up with the active threads.
I seem to always use "Active Topics" first. If I've been away for a while, then I'll look in the individual forums. Sometimes I look in the Maintenance and the Problems forums to see if there are any threads with no replies (hate to see questions go unanswered)
