 User types is the page that concerns direction administration. Here the administrator can view, add, delete and modify User types

 There are 5 sub options in this page, denoted by an extra link part:

 - &add_user_type=1                       When we are adding a new user_type

 - &delete_user_type=<user_type>          When we want to delete user type <user_type>

 - &edit_user_type=<user_type>            When we want to edit user type <user_type>

 - &deactivate_user_type=<user_type>      When we deactivate user type <user_type>

 - &activate_user_type=<user_type>        When we activate user type <user_type>
