I Built a Network--Now How Do I Use It?

I’m looking to make a career move and am thinking about contacting the HR representative from an internship position I once held. She now works for another company, and it’s a place I’d like to work. What is the etiquette for contacting her? When I began the internship, we quickly found out that we had lived in the same dorm in college, and we’re now “Facebook friends.” But the fact is, we haven’t spoken since my internship ended.

What is the appropriate way to contact someone that previously hired you?
