I've had this post on my mind for a while. What really inspired me to put it together was an email from reader Wamphyri as follows:
Although I've been playing WoW for a little while now, there's still a few things that puzzle me within the game. My main problem is the abbreviations everyone uses in chat. I was recently in IF (yeah, I know that one now!) and someone in trade chat wanted to buy (wtb) an enchant for DPS. The guy asking was a level 50-something mage, so I thought I'd send him a whisper (apologising for my noob-ness, of course) to ask what DPS meant. He replied quite quickly and told me it meant Damage Per Second. He found it quite amusing that I didn't know, saying that he has the same trouble himself regarding this issue.
