In the top left side of their website it says "Ask SCORE" and you just click there. Next, you can enter your question and it will provide suggestions of mentors or you can click to select by industry or state. I checked to see if there was someone near me and there was so I picked him. In the areas I skimmed I did notice that women were seemingly under-represented but there were a few. Not that men don't have equally valid advice! Just might not be the place to go for a wide variety of female mentors.
Another plus is there are language options in case english isn't your primary language!
I get the impression that how you want to set up the mentor-ship is up to the parties. You can communicate through SCORE only or, as in my case, the mentor might send you their email address. I don't see why, if you found a willing party, you couldn't meet face-to-face.
As a side note - It drove me crazy I couldn't use my browsers back button but had to use the one they have built into the site. I'm sure there is a technical reason for this (right, Tess?) but it still drove me nuts!
