Quick Signing of VBA Code

I've been doing some VBA programming To send important emails to my phone automatically, and was getting all kinds of security warnings everytime it ran.

I found this nice little article on how to create a self-signed digital signature that can be used to sign your VBA projects. Quite Handy. What would be even better is if I could use my already existing PGP/GnuPG key that has been signed my many people. Then it could REALLY be trusted... but of course those keys don't show up as part of the Crypt store in windows.
