Topic: 20 day buddy key
~20 day buddy keys subscribed accounts can use to invite brosefs to the game, if the brosefs sub then the account who invited them gets rewarded with either 30 days to sub-time or an ICE (their choice). Only works for brand new accounts.
I'm suprised you haven't ripped this off from EVE a long time ago, it's a great way to motivate existing players to get more players.
