Need to give members more choices rather than restricting them to prospects that you think are suitable.  Give your members open access to all members and when they like someone they can let you know to contact them on the member's behalf.  And go from there.  It's not just about interests in a relationship its also physical attraction.  So with high monthly membership payments and members blindly waiting for a match to come along only to be frustrated that this absolutely is not your type.  Members should make the choice from the member pool who they prefer after looking at their pictures and self descriptions and interests. Follow up should be by matchmaker.
