GLB2 is more for casual users. Pretty streamlined and user friendly. You just aren't able to get as in depth with your playing calling and defensive schemes. But very fun as well. You also have 2 free players on GLB2 when you sign up. So you have the opportunity to play for free and learn the game.
There are user guides for beginners in the forums. If you have questions, ask them. People will help you.
