Brian wants to know if there's a good third party utility that will allow him to tag his email. Leo says that MailMate allows tags. It's like a power tool for geeks.
He's also looking for a good file vault. He wants one that will allow him to be the only one who can encrypt the files. Brian likes Tresorit, because he's the only one who would have the key. Unfortunately that limits what he could do with it. It also uses a "patented encryption," which makes Leo nervous. If it's proprietary, that's a bad thing if they go out of business. But no one would else would have the key and it will sync over a variety of devices.
