The Request menu links to the Request page. It is generally located next to the Main menu:

Request link, here replaced by a cart image.

The link <a> contains a <span> with the number of properties added to the list. They both have the class requested-properties-[number of properties added to list]:

<div id="requestmenus">
	<ul id="requestmenu_1">
		<li id="requestmenu_1-1" class="e-1 single">
			<a href="/inquiry" title="View request list" 
			class="requested-properties-1">
			<span>View request list</span><span 
			class="requested-properties">1</span>
			</a>
	</li>
	</ul>
</div>

It can be styled so that the <span> is not displayed when no properties have been added:

<span> with requested-properties-0.

If at least one property has been added:

<span> styled with a bubble count.
