Program features:
* Cooperative multi-user text editing over the internet.
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.
* Multiple text cursors visible on the screen.
Every user has their own color. Every cursor movement and text changes are simultaneously visible on the screen by all users...
