Team membership policy

There are four kinds of policy that describe who can be a member and how new memberships are handled. The choice of policy reflects the need to build a community versus the need to control Launchpad assets.

Open
Membership is open, no approval required, and subteams can be open or closed. Any user can be a member of the team and no approval is required. Subteams can be Open, Delegated, Moderated, or Restricted. Open is a good choice for encouraging a community of contributors. Open teams cannot have PPAs.
Delegated
Membership is open, requires approval, and subteams can be open or closed. Any user can be a member of the team via a subteam, but team administrators approve direct memberships. Subteams can be Open, Delegated, Moderated, or Restricted. Delegated is a good choice for managing a large community of contributors. Delegated teams cannot have PPAs.
Moderated
Membership is closed, requires approval, and subteams must be closed. Any user can propose a new member, but team administrators approve membership. Subteams must be Moderated or Restricted. Moderated is a good choice for teams that manage things that need to be secure, like projects, branches, or PPAs, but want to encourage users to help.
Restricted
Membership is closed, requires approval, and subteams must be closed. Only the team's administrators can invite a user to be a member. Subteams must be Moderated or Restricted. Restricted is a good choice for teams that manage things that need to be secure, like projects, branches, or PPAs.
