Sign yourself and a buddy up for a free account. It doesn't do anything nasty with your e-mail address, and using it for 30 seconds will make it clearer than this explanation: We have acceptable systems for writing code alone (text editors), natural language alone (word processors), and code in teams (version control systems). But writing natural language in teams is a /huge disaster/. People put up with ridiculous systems like mass-CC'd e-mails of Word documents. So Draftastic is like version control for prose. If your group is writing a report, you pull up Draftastic and write it at once. No lock fights. No accidentally typing on top of someone. Everything updates live (no Flash, just Ajax, and it works with JS off too). It's like a whiteboard, or a whiteboard-model collaborative editor, only it's designed for actual work. You get histories, diffs, a permission system -- things we rely on in coding but haven't learned to ask for in natural language. Draftastic is a business venture by [http://pseudomammal.org/|Nick] and me. The more bug reports and feature requests the better. Enjoy!
