I actually did this for WoW, but, it works for FFXI too. Here's the post I made in the WoW forum for all you FFXI users.
Please click my link for telling you about this, thanks.
I saw this on google today so I decided to try something
This is really easy. I simply posted a link on IGN to
http://FreeGameCash.com/index.php?referral=20000018
In 1 hour and 14 minutes I had enough referrals to get my first batch of free Gold (or Gil). I had to repost on IGN a few times, but, it's really easy to make another account there. So, I then went to a few other smaller boards and posted, another 40 minutes went by and I had enough referrals for another batch already.
I am telling you how to do this so hopefully you will use my link when you go there. It does not effect you one bit to do so and now you know how you can get tons of free Gold too. Thanks to everyone that uses the link when you go!
And Enjoy all the free Gold (or Gil)!
Hopefully this will earn me Premium, since this really works and it's very easy.
