I would like to participate in this discussion, unless it matters that I have only TD'd on fibs, and never played a live game, let alone a live tourney.

I also have read back, so I understand the history of all this, as has been written in the threads.
You all know I don't get involved in past personal BS between players, so my one rule for my tourney is that any old bs gets left out of it, in respect for me and my other players. I'm not so naiive as to think that people don't get hurt by what others have said or done in the past, and that to see certain people online brings up bad feelings, resentment etc. I know people have a past, I know people dont always get along with each other. But I also know that I have no issues with anyone on fibs (and you can start naming names, but i really dont have an issue with them either, they have the issue all on their own), therefore nobody should bring their issues to my tourney. As I have stated in the past, and will stand by... anyone brings their sh** to my table, their opponent will be awarded the win, if I catch it happening. I don't always watch games, but I do drop in from time to time just to see if everything's going okay. There is one player who has used my tourney in the past, to act up, and when this was pointed out to me, I kept an eye on that player. When I saw for myself what was going on, he was banned from my tourney for a week. After that week was up, he was allowed back in, with a clean slate, and has never to my knowledge done that particular thing again.
I don't see the reason for a whole list of rules, beyond "be nice, or be silent, or be gone". Which means, be nice to the other players in the tourneys, or shut the hell up and play silently, or if you really can't tolerate the sight of them, resign from the tourney. This has happened in the past, and I have respected the player's right to leave, if they told me they were about to do so. There's only been one occasion where it affected the running of my tourney because I lost the fourth player, but that was when I first started out, and it hasn't been an issue since.
I haven't, to my knowledge, had any issue where someone has gagged or blinded another player. Either it didn't happen (which I doubt because I know some people have others on permagag) or nobody complained about it. So for the life of me, I don't understand it. I don't see the need for making rules for watchers, when the only tourney rules that should be made, should be for players. If someone has been played out of the tourney, then that's it in my view. If they want to watch the final, no worries.. but unless they receive the go ahead from the two players in the final, they shouldn't chat in kibitz. If they do, or if the players choose not to see any chat, they should be able to gag all watchers at their discretion so that if one does accidentally chat in kibitz, the player won't see it.
But I leave those choices up to the players themselves. I'm not going to demand that players keep all those enrolled in the tourney ungagged/unblinded. That opens up old bullshit to be able to free flow again. I'm also not going to police the watchers to make sure they don't chat in kibitz. Personally, i love a good chat, and don't give a sh** about people chatting in kibitz. Roll up, watch, chat, whatever. Keep your game opinions to whisper though, or you're gone. Simple. But that's in my own games, and is also subject to the permission of my opponent.
That's my two cents, for what its worth from a non-league'er who has never played a live game.
