Drop box provides a way to sync files between home and school. It is a free service for a tiny drop box, 2GB. It can also be used to share files. It is is not the same as having a web site. It is strictly for sharing files.
I would recommend it for Grad Students who are working on papers at various location. Keep a thumb drive back up, but work with files directly on the drop box site.
It can be used with Power Teacher as a place to store homework pages online. You can probably store hundreds of word documents assuming that they have no imbeded pictures.
