Dear 100 Hour Board,
Computer privacy, and freedom of information concern me greatly. I would like to incorporate PGP encryption into my email client (thunderbird, and yes I run linux) but I am not sure of something. Does the recieving party need PGP also to decrypt it or does the key go with the email (I don't think this is the case)?

If you PGP encrypt the email, then yes, they need PGP to read the message. But if you just sign it, then the signature goes out as an attachment in a separate file. The message itself is still legible, but the signature can't be checked unless the receiver has PGP. It just shows up as a file called "signature.asc", which is occasionally confusing for the recipient, but a good way to tell them that it's worth being concerned about information security.
If you want someone to sign your key, send me an email.
