All I need to know about Wikipedia I learned at these three pages;

• WP:FIXTHEPROBLEM -Don't ask someone else to do it. Unless you can't figure it out, and until you've tried, don't just tag it and leave it for someone else to fix.
• WP:BOLD -Wikipedia can absorb some pretty big mistakes and no one will be hurt. There is no cost to reverting so it's better to be wrong big than right and silent.
• WP:CIVIL -Just because they're wrong doesn't give you the right to be a jackass. How embarrassing would it be if it turns out they actually aren't wrong?

Everything else (technical skills, policy, or otherwise) is just icing.
