Online communitas

Hello Forbes,

I happy you joined me, in this site. As I told you, it's a good omen for wechange: this site has been recently created with the idea to have it become an active community working for change.

http://www.wechange.org/creating_communitas .
Your books deal with "real world" communitas, as opposed to the "virtual" community that I hope will soon develop within this site.

I wondered: what similarities, and what major differences do you see between those two kinds of communities?
Are there online communities that more like "communitas" than others?

I hope you will guide me to make wechange one of the best communitas online.
