Creative writing, and 'book' publishing

I'm playing around with this lovely 'book creation' site, where students can use images and write text (poetry, long form, chapters) and "publish" it. I can see several uses for creative writing!

You can create a teacher account (free, I"m not sure at what stage pricing starts) which can then create monitored student accounts, or students can create their own.
