I ran across two things for Gmail users today.
Adam Pash at Lifehacker has posted a tutorial 
of tips and tricks for getting the most out of Gmail. It even has video clips!
Among other things, he talks about some scripts for the Firefox extension Greasemonkey which add very useful bells and whistles to Gmail’s web interface.
Another Greasemonkey script promises to bring basic encryption to Gmail. It first encrypts the email into AES and then uses the RSA algorithm to encrypt the message again.
