Make them all sign up first and then sell to them through the power of the email...Or you could just do what lazy people do and shove adsense on there. Flower delivery affiliates? Chocolates? Anything that the would-be dater might need.
Make it free membership for ladies and free sign-up for guys, girls can send messages for free to boys but the guys have to pay to reply or send messages!
you can run affiliate ads for dating sites which pay pretty good commission. you can find the programs under CJ or LinkShare
and don't forget to restrict girls from messaging other girls, otherwise boys can disguise themselves as girls and can benefit from this "free for girls" thing.. lol
Hey thanks for replies. I really cannot think right now how to go about this as quoted above. Any further ideas please?
