I think it would be a good idea if the person who invites someone into a game could retract the invite. I have recently sent an invite in error so now faced with the wrong partner joining the team, also i have sent invites and then realised they are not active online at the time and wish to change but cant as any pm is not going to reach them, so there is then a frustating 24hr wait for it to expire, this will sometimes lead to other players dropping out especially if they are limited to 4 games. also if you are organising several different games as people join or decline you realise that some of your invites would be better placed for a more balanced game particulary doubles games. obviously if someone has accepted the invite it should remain. But i feel this change could improve the management of games.
I await your thoughts.
