If you are concerned about someone knowing you have visited this site

You can alter the history of your web browser.  However please note that this is not a failsafe way of making sure that no-one else knows that you have visited these pages.  Also, it is better to delete specific sites from you history list rather than all the sites as a completely empty list can be incriminating.  You might find it easier to use a web cafe, library or a friend's house.  If you use email make sure that the password you use cannot be guessed by your abuser.

Internet Explorer
Look on the toolbar, there should be a button called History.  If you click on this the history list should appear.  You can now delete the history logs of whichever sites you want.

Netscape Navigator
Look in the menu bar at the top of the browser and go to Communicator and the Tools and then History (short cut is Control & H) you can now delete the history logs of whichever sites you want.
