The league plays on three courts in two 70 minute time slots - 7:00 until 8:15 and 8:15 until 9:30.  The format and basic rules are the same as the men's and ladies' doubles house leagues, except that particpants play together on courts regardless of gender.  You could have three women and one man on a court, or four men, or three men and one woman, or two of each.  The league is played using a progressive format, therefore players sign up without partners. The league is open to all skill levels.
