Yes, the ads are created by the widget application from the Wordpress website. My site is timothywtron.dreamhosters.com and the ad that I'm trying to manually edit is the second one down on the screen, the one for Goodreads Giveaway.
I'm trying to insert the Goodreads Giveaway into the html file where the widget is creating the ads. I'm not sure this is allowed since the widget is inserting the code.
I'd really like to know where is the index.html file that is allowed to be edited?
Any ideas would be greatly appreciated.
