Adding @ chat for the admins would make it harder for trolls to get away with things. Like now if I had to report something to the admins everyone would be able to see it, and the troll would be able to delete his stuff before an admin could come.
This would be nice, allowing people to call for help quickly by sending @ [problem] directly to all staff and not letting the troll/rulebreaker see the message. I know that's happened a couple times where people claim that the rule breaker stopped once I was called over.
Something that is currently being discussed. We would love to have something for regular players to message staff in a server.
