Oh yes, time for me to abuse my position and spam a bunch of lists! :)

memberdb is the membership database software i’ve been hacking off and
on for a while now, and is being used by Linux Australia.

In it’s current form, it’s visually not very pretty – but the backend
database has had a huge amount of design (and redesign) work put into
it. This release is to encourage feedback, patches and volunteers.

It’s also out there so that other groups can look at it as a possible
solution to their membership database needs. Okay, realistically,
they’ll need a lot of work on it before it suits them and not us. It’s
called contributing dudes!

Yes, there are bugs. Yes, probably a security issue or something that’s
slipped me by – open source, peer review – all good.

Anyway, go have a look:

even better, grab the latest sources and start hacking! esp if you’re a
XHTML and CSS guru – i need them :)
