I signed-up for the free membership, and you can't contact other members with the free one. Also, there's a side-panel with an offer to join another dating service displaying tons of local women. But there aren't tons of local women on Fling once you join up (only in the advertisement). There's only a few, and they aren't paying members and/or don't have a pic or ugly.
A famous actress' pic is displayed for someone living in Mexico. If you email a question, they'll reply with a request that you call them up on the phone. If you indicate you don't have a phone, they'll not reply. Probably some of the less attractive women are actual paying members that you can contact if you pay the fee.
