The guys over at LFG got some invite codes from Wargaming. There’s two different invite codes, but I am not going to tell them to you so you have to go check out their site.
They are one of the good guys in the community and are currently running a kickstarter to try to get funding for their game project. So go check out their site, and the more info link below to get the 2 codes getting you either:
T2 Light Tank
1 day free premium
7-day premium account
Once again go check out their site and if you have a little money to spare check out their kickstarter too. I am making you do it anyway
