Who is allowed to do what is a big concern and often permissions must exceed what would be wanted for a particular user in order to grant access to one or two features they need, but then overextends their access to other features.
The ability to add users to a project (and thus to the Account members) is something that can get out of hand quickly and there is no way to track who added a user. It would be terrific if the Members Report could include who the user was added by. This would go a long way in helping us maintain order within the system.
