Crocodoc is a simple, online document sharing tool that provides users with the ability to edit and collaborate on documents without requiring an email address. Stickies and drawing tools are available and they can be applied to several types of files, including PDF files. The ability to password protect an online document is an added bonus that makes this tool potentially useful for teachers, students, and parents.
Upload a document for collaboration, then share the link via email. It's easy and works well when sharing with others outside of Gmail.
