Feature Ideas:

• User Created Groups — Ability for users with the right permission to create a new group.
  Public Groups — Anybody Can Subscribe
  Private Groups — Invitation Required
• View Invitations — User has to be able to view groups they have been invited to and accept or reject.
• Group Home — Lists Content added to the group as well as comments on the group. Perhaps a per content type drill down. So groups galleries, groups blogs etc...
• Per Group Theme — So that each group can look how it wants.
• Per Group Language — So that each group can be displayed in the language used by the group.
• Categorizable groups — We should be able to stick groups into pigeonholes.
• Group Listing and Search — Ability to list and search groups as well as browse by category.
• Comments -> Email — Ability to send comments on the group via Email
• Email -> Comments — Ability to send email to comments on the group — Should manage threading properly if possible
• Track recently visited groups for easy back navigation.
