The TT community is built upon not only the contributions of more dedicated members, but also through the postings by many curious newcomers. All of us were newcomers once, even those careful or lucky enough to have avoided common mistakes.
Newcomers are prospective "respected members" and are therefore TT's most valuable resource. We must treat newcomers with kindness and patience — nothing scares potentially valuable contributors away faster than hostility or elitism. While many newcomers hit the ground running, many others lack the knowledge about the way we do things.
Remember Hanlon's Razor. Behavior that appears malicious to experienced TT'ers is more likely due to ignorance of our expectations and rules. Even if you're 100% sure that someone is a worthless, no-good troll, conduct yourself as if they're not. By being calm, interested, and respectful, your dignity is uplifted, and you further our project.
