Sorry Mugz, I've no experience of wooing fair ladies I've been with my partner since I was 15.
I know a couple of people that use online dating, with some success, I would just apply the same rules as you would IRL, don't over think it, be yourself.
There isn't a manual that I'm aware of, I'd ask her about about her interests in music, film, art maybe, I'd avoid being to pushy to begin with the girl I know who has used online dating quite a bit said she got quite a few blokes sending her total filth and that if she had wanted that she would have signed up for that sort of site. I'm assuming your not using adult friend finder :D
