Good luck finding someone to help you learn. I get at least 5 IMs a day from people asking me to "teach them gs2" as if it's some small lesson in a math book or something.
If you learned some other programming language like C++ or Java that might help you better. People seem to have the hardest time learning the concept of "Object orientation" with GS2 as it isn't a command based code like GS1 was.
