Well, the best I can suggest is you could possibly look through the "working with Platform Builder" board for interesting information. It's kind of hard to give that kind of advice because PB can do so much, and it'd be easier to give a more precise answer if you could narrow down stuff. PB has so much, newcomers should just test everything in PB, and do some more testing. I learned PB just by doing experiments. That's how I learned.
