Make Gmail fetch mail from a POP email account

Ok, this isn't really a Linux tip, but it is cool. Since it seemed to get too long, I have decided to break this down into two tutorials. In the first part I will show how to set up Gmail to retrieve message from your POP mail accounts. In part 2, I will show you how to coufigure an email client such as Thunderbird for an IMAP server.
 
To let Gmail get mail off your POP server do the following:
1. Log onto your Gmail account. If you don't have one you will need to sign up.
2. Click on "Settings" in the upper right hand corner.
