Resume Question

Simbatron

Hi all,

So I am in AmeriCorps, and because of the structure of my program I get the opportunity to do a LOT of volunteer work. And when I say a lot, I mean volunteering for single events for around 10 different organizations. How should I put this in my resume? Should I leave out the more insignificant stuff, or just write something like "Volunteer for X, X, X, X, X, X..."
