Everything depends on what you're looking for. In my opinion, volvospeed message board is not only the most active but also the best in terms of advice quality. There was a post few days ago complaining the lack of answers to postings. I guess some of us got a little bit tired answering the same questions (the best oil, brakes, fluids, etc) over and over again because no one bothers checking the archives anymore or the search engine doesn't work. So if you want to use quality and availability of advice as an indicator I would say some of the other sites are getting much better than this one. But if sheer quantity is the measure then brickboard may still be close to the top.
