Go to the menu bar at the top of the page:
Click on Tools and when the menu drops down click on Internet Options
In the box 'Temporary Internet Files' Click on Delete Files, when the pop-up box appears click on OK
In the box 'History' Click on Clear History, when the pop-up box appears click on Yes
It's important to note that all the pages you have visited will be deleted from History not just the pages from the Get Connected site, so you may want to visit some of your other favourite websites to cover your tracks.
