With MoonEdit every co-author can edit the shared document at any time, from any place, and at the same time! There's no need to send files via FTP or to compare documents when multiple users need to make changes to it independently.

Every user has their own color. Every cursor movement and text changes are simultaneously visible on the screen by all users. Users can view the history of changes from a multi-user edit session. This is especially useful if you want to check out what other users have changed since you were away.
