I searched but didn't find anything along this line & haven't found how to do this if it is possible

1) change the game size in a private game

    a) not all invitations were accepted or some were ignored

2) un-invite a person (they are taking up a slot in a game and haven't responded)

3) invite more players than slots and it is on a first come basis

All of this is to help with private games when I want to play with friends but they may not always want to play.  (especially for the first time, when I use an email)

IF there is a way to do any of this please let me know!!  Thanks

#1 I don't think you can do - would be nice though.

#2 - I don't think they actually take up a slot.  Someone else could still join and the game will just start without them if you get enough players.

#3 - You can definitely invite more players than slots.  That already works.  Just when you create the private game, invite more people.

Agree with Ozy.  

And if you have already created the game you can go back into it and invite more people.

Thanks for the replies.  I don't know why but earlier I could not add another person.  Now I can.
