3. No ad hominem attacks. Attack the subject, not the other person on the thread and keep the discussion civil.
4. No spamming or commercial endorsements. These get deleted immediately.
Tip: Beware of putting hyperlinks in your comments–especially at the end. For some reason, Blogger interprets these as spam.
