Adding New Pages to the Site
(See the Plone 2.0 quickstart tutorial for more on editing pages in Plone 2.0.)
The first thing to realize when adding a new page to your site is that Plone has more than one kind of "webpage". The most generic type of page -- the one that will comprise most of your site -- Plone 2.0 calls a "document". This might be a little confusing, because that word carries some computer baggage thanks to Microsoft Word. However, it's just a normal webpage, just like the one you're reading now.
Plone uses other kinds of pages for more specialized purposes, and each one has at least one feature that sets it apart from the others. You can see the full list of kinds of pages you can add to the site by logging in and looking at the Add New Item dropdown menu on the page. (It's the menu in the upper right-hand corner of the main content area, within the thick top border.)
Here are the types of pages that ship with a normal Plone site.
* News Item
Adding a New Page
Simply click on any of the page types from the Add New Item menu, and it will create a new page of that type in whatever folder you happen to be in at the time. (You can get a clue to what folder you're in by consulting the breadcrumbs for the page.)
