Muut, like with many community platforms, has levels of users. Each level denotes the level of access to settings, control, and contribution.
This is the basic level, everyone who signs up and joins your forum starts out as a user. It allows users to start topics, reply, and contribute to the community.
Moderators have all the access that users do. They can start topics, reply and generally contribute. Moderator access also includes the ability to delete, move, and retire threads.
Administrators have all the access that users and moderators do, but can also change your community settings. They do not have access to account/payment settings.
This is you if you've started a community. You've got all the access and abilities that Administrators have, but you can also manage your payments and subscriptions.
