Guys.

Please do update us if this has been updated. I am unable to remove internal users from a project.

Please let us know how we can remove internal users from a project. Unable to remove a user. Has it been removed online?

Agree with Sanjeev on the points made. Also at any stage of a project (which is already created) The account manager/project manager should be able to add new user to the project, since there would be a case that new testers or developers have been assigned to the project.

There was a way to add and delete users.

As Scherbakovden said if not everyone in the organisation would work on every project. There are only certain users working a project. The account manager should be able to add or delete internal user for a project

Also tester should be able to reopen a bug if encountered again.
