Allow me to rephrase, because you obviously don't know what "not being a scrub" entails. If you have a question, refer to the multitude of guides. If that doesn't answer it, post it in the corresponding guide that should have answered it. If there's not an appropriate guide to offer the knowledge you seek, search the Q&A thread. If nobody has asked or answered you question there, feel free to ask it. If the amount of information on this forum can't answer your question, there probably isn't a definitive answer yet. That's how. Next time, leave the sarcasm to me, pal. I usually hope that people will see through mine and get the point of what I'm trying to say.
Allow me to translate "By not being a scrub" into something more direct: There was a thread made, long ago, that's still active, specifically to address the amount of questions people had. There is a guide section. There are plenty of tools at your fingertips. If you can't utilize them, you are a scrub.
