Please guys, I am very flattered by the attention this is getting from such credible and notable names. As the last week has progressed I believe all of us are coming closer to be on the same page, and the very sensible suggestions are most gratefully received.
I do believe that by putting this out for contributions we will end up with a much more "robust" rule than not having done so.
I guess it's getting close to the time where I solicit a list of people who wish to be involved at some level. All that remains is to think of a good way without opening the floodgates to a whole lot os spam emails!
Over the next few days I will make amendments to the "guidelines and repost for further thoughts.
JacMac, I do like the "if it is not on the list" idea.
