Looking for Group

[Amnesthesia]

Users should be able to flag themselves as "Looking for Group" as well as be able to create a group

Groups should have an expiry option and by default expire at the end of the day.

All groups must have a Group Leader. By default, the creator of the group is the group leader, but will have an option to make somebody else the leader. The leader can not leave the group without assigning another leader.

Groups should also be able to flag themselves as private and be hidden from the view.

Groups can flag themselves as open to requests, or closed to requests. When a group is open to requests, any user can click "Request to Join".

When somebody requests to join, all members of the group receives a notification. The leaders notification will have an option to Accept or Decline the request.

Group Leaders should also be able to invite other users to join their group, and similarly, users who receive an invitation to join a group receive a notification and can directly Accept or Decline.

All invitations and requests must expire when the group expires.

Manifest Group sheet should list groups on the top of the user list and pre-add all users with their selected rigs to the group manifest screen.
