I've got 8 more 21 day trial invites to give out. If you subscribe using mine, I'll get 30 days of game time for free, while you get like 7 extra days. The game time in game is worth I think around 400M, I'm willing to give you 325M for subscribing with my referral.
If you're interested, shoot me a PM containing the email address you want the invite to be sent to. Feel free to flame the thread otherwise.
