The reason I asked for the age range, is because I know that this site is only going to get "young" people in it if the current members leave their usernames and passwords to their offspring as an inheritance.
I know that a lot of people that are older would probably go for a traditional wife, but I think a lot of younger folks are probably going to want something non-traditional. They think they may want something traditional, but if they also want two paychecks, equal rights and equal lefts, etc. then that wouldn't really be traditional.
