This girl came into my class and now i can t stop thinking about her we never met before and all i have is her email and her name help?

Sorry buddy, we're fresh out of magic love dust. And you can forget that stuff you slip into her drink when she's not looking, because that's not allowed anymore for some silly reason.

That leaves you with very few options, and most of them involve you maybe possibly looking like a creep. Looking like a creep is just a risk (along with every other guy) have to take when introducing yourself to a girl and making your intentions known. There's no way to do it without taking that risk, so stop pretending there might be one.

The options for introducing yourself vary in risk levels. Simply smiling at her occasionally and then telling her your name after a few weeks is much less risky than tattooing her name on your ding-dong and showing it to her tomorrow, and everything in between those two is somewhere in between those two. I don't know how much of a hurry you're in to get this girl in bed, so you'll have to decide how much risk is acceptable.

There is only one option with no risk at all, and that option is to do nothing and hope like hell she approaches you. I'm not saying that's the right option, I'm just telling you it is one.
