This function would be particularly useful for quickly getting hold of staff and management in situations like trolls in the chat or just situations getting out of hand when you need someone with the right authority to step in. It takes time to check the marauder's map to see who's online and tag them manually, a @staff or @management tag would speed things up and make life a bit easier for the responsible chatters (and prefects) who tend to call for backup in situations of need. 

For less urgent situations, like questions or help and the like, a tag for @prefects could also be added.

With supportive cheers from the EU prefects,

Darling Walsh
