ReadyCheck in today's patch

[Skiggity]

Ready Check is now available!
Group and Operations Group leaders can initiate a Ready Check by using “/rc” or “/readycheck” chat commands or via the context group menu.
Each member of the group will then receive a pop-up prompting them to respond. Responding will place a visual cue on the raid frame or group frame of that player.
At the end of the Ready Check, chat feedback indicates whether the group is ready or if not, and lists any non-ready players.
