Permissions required to tag a project?

Version: Developer Edition Version 8.0 (build 29455)
Objective: Give project tagging privileges to some/most/all users
Attempted:
Logged in as general user - tags option is not interactive.
Logged in as a user in the administrative group - tags option is not interactive.
Explicitly assigned all permission rights to said user - tag option is not interactive.
Logged in as admin - tags option is interactive.

So, it’s great that admin has the ability to change tags, but what switch do I need to toggle to grant the same rights to other user accounts?

Hi,

Only project admins can set / unset tags.
