The idea came to mind when using Yahoo's group service, and found out that one of the members has little to no way of effectively communicating to all the members of the group.
There needs to be a site program, similar to Myspace, that allows people to login, preferably with OpenID or something similar, and either allow people to interface with their a Jabber account, or create one for use 'on the site', which automatically includes or adds onto all the members of the Development group, and allow the people to hand set a email service to use with a group mailing list. So pretty much has soon has a person registers to the site, a preset medium between all of the members is created or identified with person so he/she can set it up with their own account settings.
Whats the point if a person can only communicate to one other person present in a group? I'm not sure if this has already been done or not, but it would be nice if there was one. Right now I do not have the time nor resources to set up a site myself.
This is just one of my many few rants of the moment.
