You can use your GoogleDrive in place of a thumbdrive to move (conventional non-googledoc) files between computers or group members. Here's how:

Sharing Assets (photos) your GoogleDrive
  1. Download all photos from the camera onto your computer's D: Drive
    (Delete the photos off the camera for the next user)
  2. Drag the files to a FOLDER on your GoogleDrive
  3. Right mouseclick, and SHARE the folder with members of your group!
