So, I went back to their site because I saw that games were running, and it's a little confusing. I thought I was signed up, because I registered for that freeroll (and never got a response), but I still had to resign up. I made an account and played my first MTT with the Gold Coins on there. I read the rules on how to get the Sweepstakes Coins, and it's still a bit confusing lol. The rules mentioned sending them a mailed postcard with your account ID and legal address on there... I make take some more time tomorrow to figure it all out. But I haven't had to drop any $ in there, yet.
Anyway, after sign-up, I had 15,000 Gold Coins, and it looks like they have MTTs going on every 2 hours with 40 minute late reg for 6,000 Gold Coins. I signed up 5 minutes before the game was to start. Finished in 6th and never had to rebuy. Won 20,000 Gold Coins plus my initial buy-in of 6,000 GC. So, I'm up to 35,000 Gold Coins. Which I think are just their free coins, though.
It looks like they're still working on the logistics of things.
