Err... here goes:

sv650.org A very freindly national site I joined on my return to two wheels just over a year ago. I know a good bunch from the Bristol, Swindon and Wales area. Some are on here. Done many rideouts with these bods.
visordown Good for news information
t595 When I nearly bought a t955 but ended up with my current bike, nice folkes though.
gixerjunkies Another national site for info on err.... let me see oh yes gixers
Swindon Rideout Club Small but very friendly group local to where I work, one tiny ride (on the way home) so far.
oh, and on here of course.

I'm also on a couple of classic old (read film) photography sites because I'm old. Rangefinder forum and a Leica forum


So no I'm not a forum junky (in denial)
