OK, I read his post. Its pretty bald, but given what I understand he was required to sift through, I understand his frustration. Here's how I would deal with this:

Post a reminder about Forum Etiquette, as I suggest.

DON'T blast everyone, just the specific few that are repeat offenders. EVERYONE on here has derailed a thread occasionally, including Cybog. (let he who hasn't sinned cast the first stone...)

Ban those who refuse to comply. Particularly if they are the source of several complaints. And I think this should require the consensus of more than one mod.

Its practically impossible, BTW, to define what constitutes "derailment" anyway. And as far as the "list" Cybog provided, its terribly restrictive. Philsophy, art, science...marriage problems... I didn't see any of those issues listed and I know that many find those topics of interest. You see my point.

Now... lets move on. And thanks, Cybog for being so diligent.
