Warcraft QNA

I would like a figure on how large of a business there is in the selling and trading of world of warcraft gold and other things obtained in the game. How much money is there in total, so basically how big is the industry, and a number figure would be much appreciated.

I just never know what time it is when I play that thing, and I’d like to be look some where and see how long I’ve been playing. I don’t want to keep doing the /time thing.

i want to download the full version of warcraft, without having to pay for it and without having to redownload the demo everr ten days. is there a way to do this?

I been playing for about 2 years now and wish to learn some lore on World of Warcraft. Should I start with the Warcraft games or read some books?
Which book should I start with?

I need contact email addresses for World of Warcraft support. Anyone able to reply with the correct information gets best answer. Thank you!
I need all of the addresses listed in text format, no links. Sorry. My firewall here at work prevents me from going to their website. And my computer at home is on the fritz…
