I have sent out that message and had quite a few girls text me back that it was the funniest thing anyone ever sent or it was the best introductory email they have ever gotten, etc...a few dense ones asked "You still live with your mom?" which I nexted, but whatever....most of them are really receptive to that email...another site I have had quite a bit of success with sending this email out to is "Hot or Not"
Now onto something else I have learned...occassionally I have had a good prospect go cold after I perhaps had over-teased them...saw the last message but never responded...I waited a week and then sent them the following:
"Hopefully you didn't take my last message too seriously, it was meant as a joke...guess I need to remember that email/texting isn't the same as talking, people can't hear the tone of voice...anyways, you seem like a pretty cool person and I would be interested in getting to know you better...that last part wasn't a joke this time, it was serious
"
Both times I have sent this email, the girl sent back something like "lol ok, here is my number, text or call me..."
Cool part is they gave me the number without me really even asking for it, which is always a good thing...
