The common convention in web-sites is for the top-left icon to link to the front page. See github's logo for instance. According to our chat on IRC, we agreed that CPANHQ should do it too.
I tried doing:
But firefox wouldn't link the background image which happens to be a background specified in the CSS stylesheet - not an <img src=" element.
OK. github destroyed my TT/HTML markup. Trying again:
<h1><a href="[% c.uri_for( '/' ) %]">CPANHQ</a></h1>
