User can be management from within the user management section. From here you can add new users, delete current users and update the users account level. We currently have two account levels for users, standard and administrators.
The user permissions panel can be found within all projects,from here you can choose to assign and unassign users to the project. Administrators have access to all projects that belong to the account in question.
User / Issue Allocation
When updating or creating a new issue you may choose to assign responsibility for the issue to an inidividual user. A user is then easily able to filter issues assigned to them from within the ticket list section.
