So basically, you click this link of mine here and then sign into (or sign up for if you don't have one already) your Paradox account. Making an account is completely free (no payment details or any other such nonsense required), and used for pretty much all this publisher's (Paradox) games.
Once you sign into your account, I get credit for having "recruited" you, and that's all you need to do. Feel free to recruit others by posting in this thread, once I give the all-clear.
Really simple, but hard to find anyone who hasn't already been recruited.
Thanks for your help.
Here's the plain link in case CAG's referrer fucks it up -> https://www.survivin.../invites/DjeQzY
