Yeah that doesn't sound like a great way to circumvent the issue. A permission would be perfect. "Can group tag" - if yes, they can use the @UserGroup tagging if the group is taggable, if no, they can't. They can still tag normal users of course via their usernames and what not. You say people can still copy/paste staff usernames but I'm a bit confused, I don't really see what this has to do with a group tag permission? Sure people can copy and paste usernames but they can do this anyway as it is, regardless if group tagging is enabled or not, right? If so I'm not sure what difference it will make. Sorry if I'm missing something; just trying to understand. At any rate this isn't anything crucial, just figured others might find it useful. Thanks for considering it.
