Ed has over 500 emails in Gmail and he can't find them. They just aren't there, but Gmail says they are there. Leo says that the default of Gmail is to archive, not delete. If you click on the MORE button on the left, you'll find a folder called ALL MAIL. Every email should appear there. If you don't see them there, they are gone. Also, check the archive.
Pamela is so inundated with spam, she wants to get rid of her Gmail account. How can she back up the email she wants? Leo says the concept of cleaning out your inbox is called INBOX Zero. It's basically spring cleaning for your email account. Leo says that the archive is designed to remove all the email you don't want to see, but still have access to it by a searchable database. That's much better than throwing it away and realizing you lost something important.
