Manage tags
From the Tag Management tab, you can view, edit, and create tags. Once you add a tag, users have access to it for their projects.
Note
You must have project or organization admin permissions to complete this task.
Select Admin > Project, then select Tag Management to add, edit, or delete tags.
Select the option you want to modify the tag: Add tag, Delete tag, or Edit tag.
In the window that opens, complete or change the information about the tag.
Select Save.
From Single Item View, any user can now add the tag to their projects.
