LOL, i am a freeroller and GTDer because I have played texas hold'em for only 2 months, I need to train my skills in freerolls. I am afraid lost money in ring games because I am a poker newbie.

And I also join GTD, just don't like ring games.
You'll get to liking them eventually, I'd wager. Ring games are great for when you're relaxing and not wanting to play fast---when you've got time. In a ring game you just be patient and watch until your moment comes. No raising of blinds so no rush to get ahead, just slow and fun.
