Meepers, Google docs is really easy as far as I've found.  Everyone *does* need to have a Google account, but you can set that up in no time.   I think they changed the name to Google Drive, actually, but your drive account stores all sorts of things.  One of the options is to share the document, so each player can share with their GM.  You can even upload things you created in other programs like Word and Excel.  
 
 Maybe this will be helpful for you:
