Editing Top Nav Help

I was hoping of adding an email field into the top of the page.
We are using the genesis theme.
Below is what I want to edit and place a generic email href in.
Any help would be appreciated.
Thanks
Vod

<div id="topnav">
	<div class="topnav-left">
		<p>March 12, 2012</p>

	</div><!-- end .topnav-left -->
	<div class="topnav-right">
		<p>
			<a rel="nofollow" href="what">Posts</a>
			<a rel="nofollow" href="feed">Comments</a>
		</p>
	</div><!-- end .topnav-right -->
</div><!-- end #topnav -->
