Calliope is a Free Software version of the back-end for Yahoo! Groups. Y!Groups is a cool service that makes it trivial to form, organize and maintain communities online, but the Yahoo! legal team notorious for making arbitrary decisions about which communities are worth hosting and which ones aren't. Strong, active groups have discovered that their community has been disappeared without warning, membership list vanished, archives disappeared. When Calliope is available, anyone with a little server-space will be able to set up a community server with better policies than Yahoo's.
Calliope really needs developers. If you wanna hack community systems, sign up at SourceForge and keep the net safe for even those groups that Yahoo wants to rid itself of.
