I tried to add a tumblr icon, but am having issues getting the icon to show up correctly. Not sure what I've done wrong.
'tumblr' => array( 'label' => __( 'Tumblr URI', 'ssiw' ), 'pattern' => '<li class="social-tumblr"><a href="%s" %s></a></li>',
(I haven't posted to StudioPress because, honestly, I'm not really sure where to post there anymore. I searched the old forum, not real sure where to post in the new one (General?) and the whole multiple login thing can get a bit confusing. My apologies.)
