Here are 2 possible options,
1. On August 28th all Cases players go into the Won backgammon rated room and have one person sit at a table and mark the table reserved. Do no play or invite anyone to your table. This will tie up all the tables. Then the players who are not sitting at the tables should start sending complaints to Won on each of the seated players. Theoretically a Won Mod will show up and remove the player who is not playing. If that happens, then another player can sit at the table and do the same thing. I would think Won might get the picture when this continues all day and no one is being allowed to play.
2. Another, and probably more productive thought, would be to have every one of us write an email to the sponsors / advertisers of Won and let them know that you will no longer be playing on Won and tell them why. Don't just throw insults about Won at them, just let them know that you feel Won has made a HUGE error in their business practices and you, as a consumer, will no longer be playing at Won. This goes directly at the wallet of the owners of Won / Flipside, and I'm sure will make them sit up and take notice.
If we don't make our voices heard then nothing will be done. I for one, do not want to leave Won, but I will not tolerate this abuse of my loyalty to them. They have wronged Cases and we must do what we can to correct this.
