# Tag user

Attaching a tag to a user is technically a "find-or-create" operation. If the tag doesn't exist, it'll be created and attached to the user specified. If it already exists, it'll only be attached to the user.

> Note: If you try to create the same tag multiple times, it'll just be attached once.
