I belonged to a singles' ministry about 7 years ago. It wasn't a dating pool. It was just Christian singles who didn't have family responsibilities so we wanted to hang out. Very platonic environment.
It was fun but, again, singles' events are sometimes too obvious of places to find dates. The obvious places often don't provide what you need. I still say let your guard down in your normal routine (work, leisure, hobbies, etc.) and what God has for you will be for you.
