A PBworks wiki or workspace is a wiki, like other wiki tools, but provides a Windows-like workspace interface by using folders to organize pages and files. The navigator—a window that appears on the right side panel—is used to navigate the folders of content. But it is also possible to just build and use a standard web navigation menu instead of (or in addition to) the Navigator.
You can move between all your PBworks wikis using the My PBworks tab above or your most recently used ones under Workspaces tab. Turn on Notifications under Settings tab above if you want to receive email notices when any page or pages are updated or comments added. You can unsubscribe later.
