Well..
What php-pro said is right... but
check out the following url for scripts on dating services...
http://www.hotscripts.com/cgi-bin/se...dating&catid=2
http://www.onlyphp.com/browse.php?pg_which=2&icat=16
you can buy or download a script and try it out, to see if thats what you are looking for...
having a script will make your task easier, however... you will need to learn more about the code the script was writen on (
i would recomend PHP)in order to "customize" and fix the site whenever needed.
http://www.php.net offers a nice and free PHP tutorial...
Good luck!
PS. Im NOT a PHP guy... altho i have used it before for small projects i know im not an expert on it. But if i can help you on any way, let me know.. will do my best.
