I found a great site explaining how to encrypt your emails if you use a Mac

Sorry, if someone can find a good PC explanation, I'll post that too.

But this Mac explanation of how to use the free version of PGP, called GPG, is amazing. It's absolutely clear cut easy to understand. I just did it, took maybe 20 minutes or less, was cake.

Highly recommend.
