Admins
In the administrator listing page you can see all the administrators of the platform:

Here you can:
- 
invite new administrators
 - 
revoke administrators permissions
 - 
see when was the last time an administrator logged in
 
For inviting a new administrator, you need to go to the button "New user" and fill the form with the admin username, email and which role will she have:
- 
Admin: to give full access to the platform
 - 
Participant manager: to give permission to only do Impersonations
 

You can invite an already registered or a non registered participant.
