Australian coupon site RetailMeNot has launched a social network atop its coupon portal.

The site allows users to submit online coupon codes. RetailMeNot's Guy King told TechCrunch that, unlike other coupon sites, it follows the Facebook model and is designed to bring bargain-hunters together.

Users can create wishlists, blog, message others, comment on and tag coupons. A feed reminiscent of Facebook's Beacon shows users which coupons friends are using. Participants can fully opt out of what they don't want shared.
