FYI this is awesome, but make sure to do ur links like this (below) in the text file : <a href="http://bla.com" target="_top"></a> When I didnt do this it tried to load the link page in the LITTLE TINY ad space. Maybe you can do it with a different target also, not sure.. Anywho, thanks for the link.
I hadn't seen that problem, but that was slightly bizzare fake html I had put in the example. I'll have to play with it. Wait...mom said not to play with it...uh never mind.
