I've made a start on some documentation for the wiki application.
Previously, I included an HTML file with the windows version of the application, and appended a paragraph every time I added a new feature. This file has got a bit unwieldy now, and not very friendly to new users.
So I've decided to write an online version of the Help which is a little more task-oriented. It's not finished yet, but if you want to take a look, you can see it here.
