Comments may be held for moderation. If they’re OK I release them as soon as possible, within minutes if I’m sitting at my desk and hear the email sound. If I’m away from my desk it may take longer, please be patient.
Spam is, of course, not permitted.
Beyond that, be polite and we won’t have a problem. Just pretend you’re in my living room, having a discussion, and act the same way you would in that situation.
