I just recruited 2 people. Yes 2 recruits will get you the chocobo mount. Then you need 3 more if you want the Twintania mount which is 15 feathers.

If they add game time to their account using game time cards you will get the rewards right away. If they use a credit card you have to wait until the 30 day free period ends and the system charges their card. You only get the items once they have paid for game time.

Again if the freind uses game time cards and adds 90 days to their account you will get the mount right away. Credit card you have to wait until they actually pay for the 90 days, if they went with the monthly route it will be 4 months before you get the mount. The free month they get then the 3 months they have to pay for for the 90 days.

The 30 days free they get with the game does not count.
