Just to be clear, I do like the idea because I've seen how it works on another, well-mannered, forum that I frequent... and it works very well. But I'm not purposefully trying to change anyone's mind - just pointing out that it CAN work - but that all depends on us. WE are the ones that make it work.
As far who "determines" one of us... well, realistically, no one is going to join this forum if they're not a Grady owner (other than the occasional spammer that already does it). Plus, we, as a group, can pretty easily weed out someone that is not keeping to a general rule of decorum.
And, again, if this "would" become a thing, we all can still choose to participate in the forum or not. If it's not for you, just don't click!
Again, my only purpose was to clear things up in case some thought it was an open forum that would be open to "anyone" off the street - it would not - it would still be Grady owners.
