Toyfolio Lego FAQ

I get asked a lot of questions about Lego. I found I was answering the same questions over and over. This is way for the Toyfolio community to have all of their Lego questions compiled in one place. I started with 10 questions, but I am sure there are many more. My goal is to make this an evergreen FAQ with new questions added as they arise. Read up and submit more. Enjoy!
