Frank is ready to finally get rid of AOL and wants to know what's a better alternative; especially for email. Leo likes Gmail because he can sync all of his devices thanks to the IMAP email protocol which keeps all email at the server level. Frank can just use the webmail version or he can use an email client like Outlook. Mozilla has one called Thunderbird.
There's no "save as" to download his email, though. Leo says he has to get out of the AOL mindset. Frank is stuck in the way AOL works. He could turn on POP in his mail settings and then it will download the messages to his computer automatically. Can he choose which emails to save? Sure, through the web interface.
