<% @title = "New Wiki Web"; @content_width = 500 %>

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

<ol class="setup">
  <li>
    <h2 style="margin-bottom: 3px">Name and address for your new web</h2>
    <div class="help">
      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. 
      Ex: the address "rails" gives URLs like <i>/rails/show/HomePage</i>. 
      The address can only consist of letters and digits.
