You have cleared the cookies it sounds like.....that means you have told your puter to not see the little hints your puter usually saves once you have been to a site.. In my opinion thats a good thing
Next ??? is do you know how to save a site you like to favorites since thats the safest way????
When you go to a site you know you are going to revisit look up top while your at the site and you will see favorites left click the favorites open then add to your saved sites when you want to go back open your browser and double click on it will ake you there..
You didn't say what you were using as a browser, but on the off chance you've got Firefox, there is an "Option" selection in the "Tools" menu (across the top of the screen). Navigate to the "History" tab and make sure the middle selection has a check next to it. Mine does NOT because it annoys the heck out of me.
