Minor tweak:
When clicking the input box, I'd like the ghost text, '<a href="http://'" rel="nofollow">http://'</a>, to be removed. Since I've already copied the URL I want to make happy, when I paste it I produce: <a href="http://http://urltomakehappy.com" rel="nofollow">http://http://urltomakehappy.com</a>, It'd be nice to not have to manually remove that first <a href="http://" rel="nofollow">http://</a>
