If you click on the publisher's name at the bottom of a fact you can view his/her userprofile. The userprofile is a kind of "business card" for each user. The userprofile can be adapted using the settings-options. There, users can add personal information (address, telephone number,...).
If you want to limit access to the userprofiles to certain groups, proceed as follows:
|1| Choose “Services” from the main menu by clicking on it.
|2| Click on the “perm”-button in the row “User profile”.
|3| You will see a list of all available groups on your platform.
|4| Choose the group(s) which should be able to read userprofiles. If you choose "users", for instance, only logged in users will be able to read the user profiles.
|5| Save your settings by clicking on "Set permissions".
