Forum:What the Heck are 'Questin' Marks'?

They seem to be progressive to some end, but I can't figure it out. Right now I'm on 4 of 5 for Followers of the Apocalypse. How do I trigger the 5th one?

you just get them for compleateing most quests they dont do anything that i know of but it is a referance to world of warcraft question marks above the heads of NPCs when you are handing in a quest
