When you're stuck, frustrated, and don't know where to turn, it is great to have a community around you so you can ask questions. There is already a lot of fantastic information available on the internet, so please be sure you take the time to do a bit of google searching before you ask the experts and thus respect their valuable time and knowledge. That said, there are those times you just can't find the answer you need on your own, and that's why this list was compiled.
