In definately interested.
I can code in blitz/amiblitz, and AMOS (its better than its reputation in the right hands, and a heck of a lot of fun), and a little c and c++ (although most of the amiga c/c++ Ive done has been porting open source software, which is a different kettle of fish than writing from ground up).
Ive also been a musician for a little over 20 years, and although my amiga games music experience is limited Im sure I can contribute here too.
Graphics are also something Im interested in. I started hand pixelling back in the c64 days, and although I stopped for a few years here and there am sure I can contribute there as well. Ive also done a little 3d stuff, firt with imagine, then a little lightware, and more recently have started coming to grips with 3ds max through university.
Ive tried over the last years to make some decent quality classic amiga games, but having to do everything yourself takes time, and with my lack or organisation I tend to become distracted and lose motivation. With others involved, and seeing other peoples work and combined results coming together more quickly makes it easier to keep motivated

My two suggestions though would to make sure the projects have some semblence of organisation, and to make sure people have an interest in the particular bit of software theyre working on. When there's no money involved it's not easy to keep inspired working on something you dont enjoy or have no real interest in.
