Pirates of the Burning Sea Buddy Key program we looked at the other day is now in place, and the official site has got the details on how to give your friends their free 14-day trial. Anyone with a paid SOE subscription for PotBS will be able to claim three keys to give away, with no expiration. You don't need to go and claim them now either, as they will be available indefinitely.
To get your keys, you'll need to log in to the official site, and then visit the Buddy Keys page to retrieve the codes. After that, you can give the keys to friends, and then point them to the game client installer page where they can download their copy of the game. To help with any questions that might come up during this process, a thread has been made on the forums to discuss the program.
