Actually, I was trying out Dolphin yesterday. Yes, you are right, for the "BASE" dolphin install, only you need to register however, the other 2 items are pretty much integrated into the system. For the 2 "optional" components, your members register on their site via a form on your site. After I couldn't find a way around that, I decided to give up on it. By the way, Dolphin is NOT under GPL, they are under Creative Commons. That is far more restrictive. Would rather go with full commercial than use that.

I really want to build a community site which is why I was using Social. I am using HostToNet. Pretty much stuck here until September. After that, I will look at some of the other options. I might try out your site... Thanks for the offer!
