There are 5 user roles that are included with every club: Super Admin, Billing Manager, Club Manager, Captain, and User.  To see what permissions are included with each user type, click on Club Settings  in the navigation tree, then click User Roles.  Click the eye next to the user role to see the permissions included with that user type.  You can also create custom user types by clicking Add Role and then selecting the permissions you would like to include with the custom user type. 

To change a user role of a connected user, click on Users in the navigation tree under your club.  Then click the pencil icon next to the name of the user, select the role from the drop down list and then click save.
