A way to deal with inactive players.
I've seen a number of teams clogged with players that seem to be completely inactive, preventing new players from joining, and thus bogging down team activities.
As a solution I recommend that players that have not logged in for an extended period of time, like say a month, be set to inactive and be kicked from a team unless they are a leader. Players would be set back to active if the log back in. They also wouldn't be included in any in game lists and rankings until active again. Team with no active members could not show in a team search or list.
