From a project's User tab, a System Admin or Project Admin adds users to the project — one or many at once — and sets each user's Role, Permissions and Access. These can be edited any time.
What the Role, Permissions and Access options mean is explained in 2.5.20. To act on many project users together, see 2.5.21.
Go to the Projects tab and open the project's User tab.
Click Add Users — the "Add Users to Project" dialog opens.
Select the Users (one or more — required).
Select the Role (required).
Set the Permissions and Access (see 2.5.20 for what each means).
Click Add.
Adding multiple users at once gives them all the same role, permissions and access.
Click the Pencil (edit) icon for a user to change their role, permissions or access, then Save.
To Assign, Remove, Edit or Delete several users together, use the bulk toolbar on the Users tab — see 2.5.21 How to bulk-manage users on the Project Users tab.
Can I add several users at once? Yes — add multiple users in one go; they share the same role, permissions and access. You can fine-tune any of them afterwards.
Add users singly or in bulk; bulk-added users share the same role, permissions and access.
Edit a single user with the pencil icon; act on many users from the bulk toolbar (2.5.21).
The meaning of each Role, Permission and Access option is in 2.5.20.
