TIPS For MAC USERS - Clearing your Cache and Cookies in Safari.
Your cache is a place where every element of the webpages you visit are stored. This is useful if you are going back and forth from new pages to old pages, or if you have an extremely slow Internet connection, because you don't have to wait for these pages to be downloaded when you want to visit them again. However, if the page has been changed, you won't see the changes, just the old version stored in your cache. For most people these days, clearing your cache will not adversly effect your Internet browsing experience. It will only improve it. Do this at least once a week.
Cookies are small files that websites put on your computer. A good cookie is necessary for websites where you have to login. They help teh website "remember" you when you go from page to page, so that you don't have to login on every page. Bad cookies are used by advertisers and spammers to gather info about where you go on the Internet. Since all cookies are very small files, the good ones are easily renewed. Get rid of all of them often.
