Whether you add a new user from the People tab or from the Team and resources section in the Gantt chart generator GanttPRO, s/he will be added as a Member by default.
An Owner can configure account roles in the Team and resources section 1. It is possible to assign a role for a particular user from the drop-down in the Account role column 2.
You can also do it from the User card. Just click on a particular user 1, and assign the role 2 in the emerging window.
Note that it is also possible to define the account role when you invite a new user.
An Owner or an Admin can configure access rights for team Members. This can be done for every project separately. So, for example, the same person can have a right to only work on personal tasks in one project, while having the right to edit and see the costs in another project from the same account.
It can be done from the People tab in a particular project.
Alternatively, open the Team and resources section 1 in the Profile settings. Click on the corresponding user 2 and configure the project rights 3 in the User card.
For an Owner and an Admin all the rights are enabled by default for all the projects they take part in.
