I am glad for you all, it is so much better when the 15 people who signed up actually do show up. I hope you had a good game and did not have to go into the river again.
I don't really see anything "NEW" in the system except it was said that a list of names would be brought to the game to check and see who showed up.

If a list of names is what is needed to get people to change their YES to a NO when they know they are not going to show up, then it should be done every game.
