Here is where I've got to on free no registration dating sites that work, and where I'm stuck. The part that keeps tripping me up is paywalls.
You can usually tell within a week whether the options here is going to work for conversations that keep moving. Nobody warns you that the upsell on sites that work is worse in smaller towns than in cities. I would settle for keeping a thread alive at this point. Would be good to hear from people I have compared notes with in particular.
Will update this thread once I have given free no registration dating sites that work a proper run.
