Suggestion: Having an @ help for users

I don't think I saw a feature like this in the gitLab, apologies if it's already in the works or been suggested.

The gist of it would be to have an @/help ping so if someone needs an edit to a title or tags or something, they can use that and it'd flag the topic or somehow show those who have the permissions that this thread needs attention. This might be helpful for users (like moi) who might not know the people who CAN do this already off the top of their head, beyond Deimos.

Let me know your thoughts or if this could be a useful feature for anyone else.
