Ive still got that WoW free 10-day Guestpass lying around here, and im willing to give it to any of you really interested in it.
If you never played WoW, and are really interested in testing it out, then comment here, and ill PM you the code.
It allows you to play for 10 days, level up to 10 and gather a small amount of gold. you can also transfer that account into a full working account on the fly, if you liked it.
you can use it whenever you want! you have to dl the game from somewhere though. im not sure if you'll get a DL link if you register the guest account (i really hope so) ... i think i remember reading, that the "guest account" version of the game is smaller in size, so thats highly possible.
