Drop.io is a free file-sharing site which permits users to privately share their files and collaborate in real time by web, email, phone, mobile, and more. Create a drop by uploading a video, photo, document, or music file, in two clicks and share with others by providing them with the drop name (URL). Size limit is 100 megs.

Use drop.io to privately share your files and collaborate in real time by web, email, phone, mobile, and more. Create each drop in two clicks and share what you want, how you want, with whom you want.

Have your students create a collection of artifacts on a specific subject and collaborate on the selection. If you prefer, you could create a subject-specific drop for and share with your students. Check out the 'How To' video to learn more about this robust file-sharing social networking site.
