Thread has a simple enough purpose. I am going to go out on a limb here and say there are many TES fans who have no idea what many MMO/Online game terms mean(myself included). Figured it would be a good idea to tap into the MMO Player resource we have here and build a collection of terms used in multiplayer online games. From common terms to more situational based terms.
So, post commonly used MMO terms and define or explain them. Possibly with some context. Like what is a griefer? What is QQ-ing?(am I typing that right?) What does RvR stand for? Those kinds of things.
