Some thoughts about groups in pump.io.

Group whould hava an ordinary pump.io account. So people can follow the group, and post (or share) notes to the group (to or cc).

Then there could be a special client (groupbot). When somebody sends (or shares) a note to group, groupbot whould share it with the followers. This would be the simplest case.

If there is need for acceptance for the group member, group owner (account owner) could create a pump.io list named "members" and manually add the accepted follewers to the list. Then the groupbot whould share the posts to the members (not followers).

If there is need for the moderation, group owner could create a new list, named "moderators" and add moderators to the list. The groupbot whould share the posts first to the moderators, and if a moderator (re-)shares the post back to the group, then groupbot shares it to members.

This could work as a prototype for the groups. It would not need modifications to current pump.io server implementation, only some kind of groupbot implementation.

Well, actually, I am not expert in pump.io, so I don't know if it would work... Would it?
