A teacher can register people in Synergeia via Main/Share/Register by simply entering a list of email addresses and assigning them roles. This menu item is only in the home directory of a teacher available. In the first form you have to provide the email address. In the second form you have to assign the system role and the language of the invitation message. As a result of this, an email is sent to each of these addresses inviting them to register in Synergeia. The email includes a special URL that they have to enter into their browser. Then they have to enter a username and a password. It is their responsibility to select a sensible username (such as their first name, last name or nickname) - teachers may want to recommend a convention for doing this, such as first name in all lower case letters). The users are responsible for remembering their passwords. They must also enter other information, such as their full name and school (or other organization) name. Users who forget their passwords can request Synergeia to send them a new one by email.

Students without email addresses can also be registered by their teachers via the menu option Main/Share/Register. There is a link named Register students without an email address. Clicking on this link displays a form for entering the userid, password, full name and school for several students. The profile (e.g., primary) should be selected for these students. Teachers can produce a report of all people enrolled in courses and groups from their personal home folder via Main/Enrollment Report. They can also search for people who have been registered via Main/Search/For People.
