Btw, anything in particular you'd like to see in a self-hosted version? Would you be using it for an individual group, or want to host multiple groups?
I think multiple groups would be nice. I thought of hosting meetings for a book club, music nights, DnD/DSA, Critical Mass or Birthday and Linux Install Partys.
Some privat, some public.
Not yet! I'm very interested in both, though - something I'm looking into. Stay tuned!
