I myself communicate with someone I know/semi-know/etc.
And set up that once we're both out of the cup we scrimmage each other for the entire duration of season, so its the same scrimmage partner every week.
I do this because I am not "flag chasing", and by doing it this way we both know who's training what and where, and that its the same lineup of guys day in and day out, and that there won't be a forfeit.
