my ears were burning, and it turns out with good reason!
There is an IRC channel, which can be reached via the freenode network, irc.freenode.net, and as von Corax has stated, the channel is #brassgoggles.
If the thought of installing and configuring an IRC client seems somewhat daunting, then you can access via the web chat at http://webchat.freenode.net/?channels=brassgoggles
There's no need for registration, you can just pop in at any time. I'm almost always about, and there are several lurkers who may be prodded into conversation, as well as regular users. If you join and no-one's talking, introduce yourself, and people will reply when they reach their respective keyboards. It isn't directly affiliated with the forum, but most of the channel's users are members here too.
Permanent lurkers are welcome
