if you;re going to tell me that my code is wrong, show me why. That way, I can either fix my code or demonstrate how you misused it (or both). Don't just say "Uh, your code suxx0rs" and walk away. That's not how OSS works.
My criteria for good software:
Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
