Question - setting up dating and social networking

hi, im new to dolphin and im trying to run a social networking site and a dating site.. everythings working fine but i cant figure out how to get the dating feature get going. do i have to run two different sites for dating and social networking or can i do it in one single site?  also can i integrate osDate with Dolphin (one login for both osDate and Dolphin) ?

i have searched for these questions on google and boonex and other places but couldnt find the answer.

thanks.
