I frequent a few others. I personally am a moderator over at Mazdatruckin.com. I find the B scene a lot more social and friend oriented, MT is more technical oriented but also welcoming to all members. I also go to diyaudio.com for advanced audio stuff. Currently looking for an active and friendly civic forum that's structured like B Scene or MT (and not arrogant about it.)
mx6.com sometimes has good information but for the most part they are lame.
