Another point connected with this. I made a private game this week, so my partner could join in later (we weren't online at the same time). After that I put it in the Callout forum, but after 1 day nobody had joined the game.
I think it would be a good idea that the player that started the private game could remove the password after their partner has entered, so that after that it just is a public game in which every one else can enter.
Edit: I see now that this is already on the to-do-list. So nevermind this post.
