Roles definition

Hello,

I would like to have some feedback about Lectora Online.

For example: Who can help to understand the difference between the roles Administrator, Project Manager and the users? I am not sure that the users guide is really good describe.

Apropos: Should we need a super Administrator if we use more than 20 licences?

I would like to understand in one or two sentence the difference between these roles.

I have understood that the administrator

1. manage the Lectora Online organization
2. add new users, manage the users list, give the right access to the users as project manager, users or reviewer, and he can reset password.
3. can communicate with the complete organization, send assigmnents and check them.
4. can create a new project, edit it....
5. can revert a project if needed

But what is the difference between a user and a project manager?
