I've kind of started using Dropbox instead email me at amalthia at gmail.com and I can send you the shared folder invite. I was having issues with connecting with google docs (and running low on space) Dropbox seems like a great way to share the ebooks without anyone having to actually visit dropbox to download anything. When I update the stories will update on your computer, or if you prefer to download yourself I can give you the shared link instead of the shared folder. the mobipocket folder is about 360MB.

Dropbox gives about 2 Gigs of free space starting out and if you use my referral code you'll get an extra 250MB.
