...and I haven't seen her before in my life. I don't use the 1-10 rating system really but for the sake of your mental image she's HB7/8 rock chick kinda thing. Which I like.

To the point - I've never used the internet for sarging before so I'm going to swallow my pride and ask the knowledge of this forum. How should I play this one guys?

Oh, and I haven't accepted the invite yet, and facebook is giving me the option of sending a message first.

i wouldn't accept straight away, provding her adding you wasn't a mistake, add you in itself is an IOI.

Play it off with her in a few messages, make her work for you hitting the accept button.

something like, (tune this because im in a hurry).

So you want to add me? you think you're ready to join my tribe?

go from there, but change that line becuase it sucks, but you get the idea.

Just ad her, then read her profile and look at her photos and send her a message about one her interests! Don't do cocky funny as she has no clue who u r, she can easily say "well ignore it" and she will never remember ya.
I added this girl who is into rock as well, and in 2 weeks I was her top friend -although she has more than 4000 random guys on her profile who hit on her none-stop-, she'd block all her friends on msn to talk to me, we web-camed alot, she calls me every now and then and ... The only problem is, she lives in the country I used to live, before I moved to Australia and We have been talking for more than a year now. But she is looking to transfer here.
All I did was, I send her a message saying "hey, how r you? As if you dont listen to Marilyn Manson ..." and we started it off from there! Instead of commenting on her pics sayin "omg you are so hot"!
She is HB9 and very cool girl btw,
so yeah, read her profile and learn something interesting about her and start it off from there!
