Pseudonyms allow you to create other names for existing users or groups. For example, you may wish to create a pseudonym "webmaster" for your "webdevelopers" group or a pseudonym "joe" for the user "joseph".
The server automatically creates pseudonyms of the form firstname.lastname and firstname_lastname for every user on the system and a pseudonym "everyone" which contains all users on the system.
You can modify or remove a pseudonym by clicking on the corresponding command next to the pseudonym.
