I dont know which forum exactually this fits into, so if it's wrong please move it. Anyway I have a client that's looking for a free/low cost online dating service script to use to start a non-profit dating service, anyone know of any?

PHP:
http://hotscripts.com/PHP/Scripts_and_Programs/Match_Making/index.html

or search google :)

I know of a free one for non profit and $250 for profit...

I'd rather pm it to you...
