Enhanced Text Problem

Hello friends,

I’m very new to building sites with WordPress, but so far I’m loving what it’s capable of.

I’ve been using the forums a lot to find solutions to problems I’m having, but this one hasn’t really come up.

I built a site which can be seen here:
http://bentrain.wordpress.com/

I noticed that some of the pages have hypertext links appearing on it, that when clicked say they’re “enhanced text” boxes (with surveys and other ads). I cannot figure out how to get rid of them.

When I view the site in firefox- nothing. When I view it in Chrome though, sometimes several links appear on a single page. (Like my contact page!)

Please help this novice!
Ben
