You’d need to edit the relevant template file in your theme (possibly header.php) and add the link manually. eg:
<ul class="artmenu">
<li><a href="http://www.earlyfaith.com/"><span><span>Home</span></span></a></li>
<li><a href="<?php bloginfo('url);?>" class="active"><span><span>Blog</span></span></a></li>
</ul>
That’s great. That created the button, but its not the correct color. It should be black, like “Blog” is.
