Can I uninstall the Zemanta WordPress extension and get the code out of my posts? I'm a little aggravated that Zemanta adds all this code to my posts. How do I uninstall Zemanta and get my blog back to the state it was before I activated the extension? Did it add anything to my database?

Help! I have floating Zemanta boxes on my blog (http://palamas.blogspot.com/)! People are having trouble reading what's there. How can I remove the floaters?
Thanks
