Adding a new page/section/article
The easiest way to add a new page is probably to edit the URL in your browser that currently looks like:
change it to the title of the new page you wish to create:
Then edit that page and save it. All done.
I have removed the "Create new page" link as it created more problems than intended. Once I get a better grip on things, I'm sure I'll find a more straight forward way for you to add new pages.
