I'm an Editor!

I'm taking a senior seminar humanities class this semester, one where the teacher decides the subject and it changes every semester.  This semester, the teacher decided to have us write a book on 20th century American humanities.  We were split into groups to do research and two editors were chosen originally.  This last week, they decided they needed another editor for help re-writing everything to make it flow properly.  They picked me!  I am a bit nervous, but very excited as well.
