In the summer of 2009, I compiled a list of basic MMO social terms and abbreviations after being unable to find such a thing on the Internet. The original list was posted over a 4 day period, which served to divide the list in retrospect. In an effort to streamline things, I present to you what I call the MMO Boot Camp, now in one continuous form. Study this list. Familiarize yourself with it. Your virtual life could depend on it. DISMISSED!
Basics:
