I am three quarters of the way through writing a non-fiction book using MS-Word and am at a stage where I am seeking feedback from lots of different people whilst regularly updating and correcting things. I recently heard of someone who created a book using wikidot.com. This concept sounds appealing, except that it would be a major effort to convert a large word document with lots of tables and diagrams into the right format for wikidot. I am looking for alternative suggestions where I can allow people to read the book easily whilst maintaining the ability to update chapters on a regular basis. It is not essential that I edit online, I am happy to edit chapters off-line and then upload. Any suggestions?
P.S. I am quite fluent in HTML, ftp etc.
