title: Set Form.values to a foreign Site without ID / Access to sourcecode
body: <p><strong>Short Process description:</strong> The User put all required information into our website ( php / mysql / js enabled). With pushing "Enter" all information should be spread/shared to all relevant counter parts.</p>
  
  <p><strong>My Idea</strong>
  Therefore I'd like to pass the information "Username, Email. Realname" to a "foreign" Mantis website (manage_user_create_page.php) where I do not have the possibility to change the code. The Target looks like:</p>
  
  <pre><code>&lt;div align="center"&gt;
  &lt;table class="width50"&gt;&lt;tr&gt;
  &lt;form method="post" action="manage_user_create.php"&gt;
  ...
  ...
     &lt;input type="text" name="username" size="32" maxlength="32" /&gt;
  ...
     &lt;input type="text" name="realname" size="32" maxlength="64" /&gt;
  ...
     &lt;input type="text" name="email" size="32" maxlength="64" /&gt;
  ...
     &lt;input type="submit" class="button" value="Create User" /&gt;
  ...
  ...
  &lt;/tr&gt;&lt;/table&gt;&lt;/form&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I already tried to open it like: <a href="http://..../manage_user_create.php?username=Whatever" rel="nofollow">http://..../manage_user_create.php?username=Whatever</a></p>
  
  <p>Is there any solution to put this Information, from my site into their one (more or less automatically) and maybe Submit() it, too? getElementById() wouldn't work, because of missing "id"...</p>
  
  <p>Any suggestions?</p>
