That's an interesting thought. Perhaps a Monk "Sins" section could be created that could allow us to post some basic etiquette rules? Personally, I can't post anything to the Perl Monks guide to the Monastery and it doesn't look like it's a possibility in the near future (It appears to be an uneditable page).
Well form and agree on the etiquette rules first... After that vote on them so a majority of the commynity can accept them? Before we post them to the person who handles the guide...
