Hello Clem.
I've been in the same fix as you, a year beforehand!
To my understanding, there's no 'center point' or person in charge (unlike, say Bit Bent, which comes attached with friendly faces!)
So, pretty much if you have questions, you need a 'regular' to answer them. Alternatively, try scrolling through ActQueer and message whoever posts their messages!
I got a rather perfunctory response that way - but I've gone once or twice anyway. It was okay. Plus I have a suit or two, as does my bfriend. It's really an 'assigned evening' rather than a group, if that makes sense. And it's pretty crowded. But a much more sophisticated crowd than one is likely to meet clubbing, and plus (being Hippo) you can actually hear the conservation you're having!
So, what queries do you have? Can I help?
Cheers,
Haps
