an HTML form. Linking is done automatically on the server side; all
pages are stored in a database.
This may sound rather simplistic, but a Wiki is a very unique way
to collaborate on the Web.
The addictive quality of a Wiki is that making pages is as simple
as making a link to them. If they don't yet exist, the page link
will be followed by a hyperlinked question mark; follow that link
and you can define the new page.
With this setup, you can update and create pages from anywhere
there is a web browser handy.
