I ran across www.clubsrt-4.com . They just moved the site yesterday, but it looks like a cool network.

That looks like a pretty cool place, but it's kinda slow. http://www.srtforums.com/ Seems to be very busy, but it isn't /just/ for SRT-4 people.

www.srtforums.com are the best don't waste your time with club srt or whatever.
