ProjectSpaces now offers a WYSIWYG online document creation and editing tool called "Shared Documents".  Shared Documents are very handy for keeping joint notes, building collaborative lists, and co-authoring papers and reports.  A revision history is maintained automatically so you can always look back at older versions.  Shared Documents can be organized within the ProjectSpaces document library and are full-text searchable.

The interface for Shared Documents maintains our objective of keeping ProjectSpaces very easy to use and intuitive while supporting powerful collaboration.
