I think wanna be is right on. I've been getting number pretty easily online recently (I've just started). I've been using pof and have been having excellent success. I'll try and get off my iPad and to an actual computer and post up the conversations. More times than not...they've thrown their numbers my way. Short playful banter that makes them wanting to keep,it going, then when they realize for whatever reason (youre on the site less, the site is too slow, you'll be unable to get to the site) they either ask for your number, or you throw yours their way non-shontley (sp?). There should be a positive response to build from via text and move the game forward.
