User Roles and Statuses

What do the different user statuses in ConfTool mean?
Can I add more statuses?

You find a list of all user statuses in ConfTool / ConfTool Pro here:
User Roles and Statuses in ConfTool

You cannot add or define more user roles or statuses yourself but you can update options of some of the statuses when you go to:
Overview => Settings => Settings for User Registration => Main Settings for User Registration and Management

Furthermore you can combine the available statuses, therefore giving you many different options.
