Are astronomy groups changing with the rise of the Internet?

I'm looking for examples of non-traditional astronomy clubs, where there are no bylaws, no annual dues and no formal structure. Yet they have active members, regularly scheduled events and sell/trade equipment, just like traditional clubs.

1. Lots of yahoo groups are kind of like that. I am a member of some of them.
2. Actually astronomers anticipated the internet by years with telex hot lines running from one observatory to another round the world. This system spread the news of supernova 1987A. But a previous answer about some Yahoo groups is good. You might also find such groups attached to some popular astronomy websites, there is a fairly active forum attached to 'Galaxy Zoo'.
