I decided to write some tutorials on how to use PGP and eventually other things, since there's so much confusion about these things. The first one I wrote is for GPG4USB. I kept it deliberately concise so people are more likely to read it, while pointing out common misconceptions, stumbling blocks, etc., and giving tips that I've learned along the way (bigger key size, etc). You can find it here http://32yehzkk7jflf6r2.onion/gpg4usb/ Other stuff that I'm planning is on the main page.
