  Each web serves as an isolated name space for wiki pages, 
  so different subjects or projects can write about different <i>MuppetShows</i>.

      The name of the web is included in the title on all pages. 
      The address is the base path that all pages within the web live beneath.

      The address can only consist of letters and digits.
