How do I invite my friends?

All you have to do is go to the server's webpage: RPG1, RPG2, or RPG3, then copy your referral ID and share it with your friends. On registration, they will have to enter you ID to become part of your referral system. If you wish to see all the people you invited, head to the same webpage as above and look for a table where all the players who used your ID code on registration are listed.
