I am currently working hard to make my novel writing software tool "Novello" available for others to use. I have laid down the bare bones of the website here: novello.sourceforge.net.

It will of course be free for anyone to use.

One of the most interesting aspects about my software is that it uses something called Subversion to store your novel document. This means that several people can work on the document at the same time (as opposed to Microsoft Word where you have to email the document around and you completely lose track of which is the latest version). This is useful because it means that your editor (my mum in my case) can go in to your book and add comments and make minor corrections.

I am also toying with the idea of starting some sort of collaborative writing project with the software. This idea is just a seed at the moment. I am not the first to try this (google for "collaborative novel"), but no-one has really succeeded at this yet (please correct me if I am wrong) so it is a worthy challenge.
