you can find us on #galaxium (
irc.gimp.org)
There is a pretty good introduction to Mono.Addins that you can find
here:
http://www.mono-project.com/Mono.Addins
Though you don't actually need to know a lot about Mono.Addins, most
of the "difficult" stuff is already written, using it to support new
protocols / extend existing protocols is fairly simple
Anyway, just drop by on our IRC channel and we will try to get you
started :)
