If you are in a major city for any period of time, you are likely to see "WTS" and "WTB". You may also see "I want to group for questing in STV" or even " LFG 2M DM PST for Info!"
As you progress through the game you will easily know and remember all of these without needing to look over anything. But, for the time being, here is a comprehensive acronym list. Not all of these are used across every server, so be careful! And this is not a list of "Leet Speak" nor of "textspeak."
