all the ones I've come across in London involve people getting together over drinks in a pub.
Gee, the extents that some people seem to go to, to get a beer, never ceases to amaze me. Really, one should be able to go get a beer without claiming to be a BDSM activist.

But really, what is the group in question going to discuss if they beforehand exclude all the mainstream books on the subject?
