Welcome, so glad you signed on. I can say I learned most of what I know right here on this forum. The answer to all questions in on this forum but if you can't find it or don't have time to look, ask the question and you will get answers. Just remember there are many ways to do things, so work out which answer works best for you.
For example, there are a lot of blades, sizes, brands, types. Flying Dutchman and Olson blades are the most popular I would guess. The size and type depends on what you plan to cut. There are charts available online that show blade size, versa thickness of wood you are going to cut. Good article here about blades in general: www.scrollsawvillage.com/topic/20398-newcomer/ But through it all there is the ones you like best, others may not. You have to practice and experiment to determine which you like best.
Remember it is suppose to be fun, and it is. relax, and enjoy. You are starting off with a great saw.
