I just use good ol'e HTML. So say you are promoting "garden secrets", you can just link your code by doing:
<a href="http://www.blahblahblah.com" onmouseover="window.status=''; return true;" onmouseout="window.status=''; return true;" target="_blank">www.yourgardensecrets.com</a>
This will link your code to the blahblahblah.com and the customer will not see any link at all on the bottom of the page, plus the link will open in a new window.
Pretty useful if you ask me.
