I have two questions here, but both deal with the new "challenge mode" in Warcraft.
1) How does one go about running an instance in challenge mode? In other words, is there something specific that you have to do before starting the instance in order to put it into challenge mode, or is it something that can be done inside of the dungeon once it's already started?
2) I noticed that there is a daily quest at the bottom of the Shrine of Two Moons (this is the Horde city, but I'm sure there's one at the Alliance also) and it appears to be a random daily for doing an instance in challenge mode. Am I correct on this?
