		  <div class='clearbox'>
			<h2>Sending the link to an email list</h2>
			<p>To invite people to participate in your survey, you can just include the link to this survey within a regular email:</p>
			<div class='clearbox'>
			  <pre>Hi everyone,
				  
Please take a minute to fill in my survey:
				  
<a href=\"$surveylink\">$surveylink</a>
				  
Thanks very much!</pre>
			</div>
			<p>You can also add a unique <code>&uid=User123</code> ID to each link, to help you record which of your contacts have responded. See the <a href='http://www.askpeople.co.uk/help/'>Help documentation' Tips &amp; Tricks</a> for more guidance on how to do this.</p>
	
			<h2>Using an &lt;iframe&gt;</h2>
			<p>Inline frames let you embed one web page within another, and are probably the easiest way to include your AskPeople survey within a regular webpage (see <a href='http://www.askpeople.co.uk/samples/iframe.html' target='_blank'>an example form</a>). You can copy and paste the piece of HTML code below into your own web page wherever you want this survey to appear:</p>
			<div id=\"codeexamplebox\" class=\"clearbox\" style='width:95%;'>
				<textarea cols=\"80\" rows=\"12\" name=\"codeexample\">$code</textarea></p>
				<p style=\"text-align:center;\"><a href=\"launch.php?action=DownloadCode\">Download this code</a></p>
			</div>

			<p>There are other ways to integrate AskPeople surveys with your site.</p><ul>
			<li>You can create your own template in the <a href='templatemgr.php?action=EditTemplate&templatename=AskPeopleDefault.php'>Template Manager</a>, making sure that you have the [SURVEYLINK] tag in the template where you want the survey form to be displayed.</li>
			<li>Alternatively, for a simple one-page form, you might choose to use a server-side include (if your web server supports them) or AJAX-based import.</li>
			</ul>
			<p>For more examples and techniques, check the Tips section of the <a href='http://www.askpeople.co.uk/forum'>AskPeople Forum</a>.</p>
