Since 0.6.0, there's a user privileges/permissions system. You can make the user "USERNAME" an admin by doing
./bin/gmg makeadmin USERNAME
An admin gets access to an Admin Panel, and when looking at other user pages, is able to revoke/give privileges. Default ones are:
active Yes admin No commenter Yes moderator No reporter Yes uploader Yes
To change the default set of privileges
This is currently possible by checking out a branch that tilly-q is working on.
