Good choice Nip, I spent the last two weeks in several different sites trying to decide which one to move my Com. into,
I tried Multiply but the members got distributed all over the place. There were links and sites everywhere.
After a lot of deliberation, I too, decided on Aimoo.
It is more user friendly, you can change the front page to suit whatever,
It has a built in Chat room and lots of extras. And MSN will migrate you over lock stock and barrel.
