either you should be able to create a league game, in which only league players can join, or people from your division (and yes i know the league is not official but still, it should be) or you should be able to do a friendly game without guests. i reckon that guests should just be banned, there are surely enough members now that you dont need to entice any more, guests just make trouble

For league games can't you use the private game and invite options?

There is no problem with non abusive guests so don't want to ban all guests.

because it is very difficult to memorise all those who are in your division. most users are sensible and nice enough to leave a game they enter by accident which is a league game, or not enter at all, but guests constantly enter and then wont leave. i know they are not obliged to leave, but if you could have friendly games without guests thats the problem solved
