I had a computer that was 4 years old too. It died. But as long as you don't have any virases, or to many favorites, or bookmarks. You should be okay. Also are you a memmber yet? if not get one, make your acount, ready and set with facts about you, and pictures if wanted, then if you'd like, you can get an icon. And most inportantly, go to images, then at the top you'll see somthing that says “send” and I'm prety shure you'll get the rest.
