There are a variety of permission levels with MapLarge. 

Users  

Users receive a login, username and password. Users are members of groups and can be members of groups in multiple accounts. Un-authenticated users are given “nobody” permissions which allow them to only view non private data.

Accounts

Accounts own resources like tables and groups and are used for billing and plan level limits like # of tables, amount of data, etc.

Groups

Groups define a set of permissions that allow actions under a specific account. For example, a group called Administrators of AccountA would have the right to administer all resources under account A.

Type of Groups

Admin:	has permission to administer all account actions, including creating groups and assigning them to users.
Editor:	can view, import and delete public and private data but cannot change groups or user permissions.
Viewer:	can view public and private data, but can’t change anything.
Nobody:	can only view public data.
