Basically, the way i look at online game is as a primarily numbers game, you can send a message to over 100 girls in the same day, more chance for success, and obviously more chance for rejection.
The method i use is this
I will send them a message saying

Hi there
How are you?
I came across your profile, and would like to get to know you, and see where it went from there. And don't worry, i don't tend to pee myself if i go on a date with a pretty girl.
Anyway, take a look at my profile and let me know either way.

Then if i can, i will compliment them on their profile, this gets fast responses, and your intentions are clear from the outset, so no confusion when you ask them out after a while of chatting.

Try it out and let me know

some of my favorite numbers game online openers:

eff u

i have an intuition about u

i just read thru ur profile. i can already tell, ur one of those types

y don't u add me before u start flirting with me.


NOTE: some of these are going to get a negative responseinitially. but online numbers gamers know that all u need is their emotional attention. the rest is game on.

It seems okay, I just think it leaves too much to her in a way.

You compliment her, which is fine I think, but at the same time I'm sure she knows she's pretty. And of course everyone wants to know her, she probably gets them all the time. You need to make sure it's YOU she wants to meet. You need to DHV and make her interested in meeting you.

Also letting her see your profile right away could come off as a little desperate. Make her work to see your profile . It's like saying hey, I'm cool! Please check me out. As mystery says, a rich man doesn't need to tell you he's rich.

Let her prove herself to you why she's worth getting to know.

I like jazestix's openers, they challenge her to prove herself to you.

EDIT: Also, saying that you won't pee yourself when you date, presupposes that you want to date her, and that could put pressure on her when she may not be looking to date. Plus, it gives her an inherent sense that you're looking something in return, which could really turn her off.
