|  | Users have different rights, as the case may be, according to which user group(s) they are assigned to and which permissions these groups are granted. In principal, a user can only see those services and contents for which he/she has been given permissions. 
 A user can:
 
 
 Register
 Change his/her settings (user data such as address, telephone number, photo...)
 Order information (notifications) concerning changes to texts
 Retrieve contents (the authorization system controls who sees what)
 Enter contents (if the services images and downloads are activated, they can also upload pictures and externally-created data files)
 Link/Associate contents with each other (link)
 Change contents (Permission settings control who is permitted to edit)
 Hide contents (Permission settings control who can delete what)
 Set permissions for new or altered contents
 
 |  |  | Permissions System: The user sees which groups the pAdmin has added and can select which groups he/she would like to grant read/write permissions to. This person cannot, however, add his/her own groups.
 | 
 
 Come into contact with other users (ping, chat
), if these services are set to available.
