Ha ha! Thanks Marc! Geek.Zone is a registered charity that promotes mental well being and social inclusion. We use Tiki because we committed to openness from day 1 (or day 0 if you are a programmer) and want all members to be able to edit everything, as well as do all the social stuff.
We actually have some voluntary Geek.Zone/Jobs available, most of which are Tiki orientated. The most interesting is membership management, as we (as I'm sure many others) need to be able to charge for membership. Where would be the best place to post that?
