Hi There! Welcome to GDS and the new world of digi-scrapping!
The classes are a great place to start -- we were all overwhelmed when we first started too and there is so much to learn still, and I have been scrapping for two years.
I found I had the most fun when I was learning new things, but if something was just not clicking with me, I moved on to something different so I didn't get frustrated. There is a huge learning curve with softwares and then wanting to do what you see in the galleries. Just keep in mind scrapping is a process, and that is part of the fun of learning. It is such a great thrill when you learn something new and then can put it to use.
Ask questions and there is usually someone around who might be able to help out.
