Set your radius for 1 mile, go through all of them then set it to 2 miles etc etc. This way you get all the girls close to you first rather than spending hours or days sifting through girls from too far away.

I just use "Hey hows it going?" maybe with their name. Is there a better way or whatever? I generally have casual conversation then say "Have you met anyone off this before/do you meet people off this?" followed by "I haven't, you seem pretty cool, want to" or something to that effect.

I have two dates set up, a possible third (they live far away), and a few conversations that are leading to it. Not bad for two days of using it. Does anyone use really 'direct' or forward ways, or particular style?

Edit: I also chat to nearly any match, even if they're not hot, and possibly see if I can set up a date just so when hotter girls come along so I would have figured out any Tinder faux pas' and got a feel for how to use it. The whole scarcity vs abundance shit innit.
