Exellent point. I'll put a signed statement of my policy in my .plan. It won't add many characters, and anyone can find it by fingering me.

I can't solve this one so easily. I have two ideas that can help: 1. change PGP in future versions (starting with 2.1?) so it doesn't ask for confirmation every time a key is added to the ring. Make the user do an active action, rather than a half-asleep y<cr> to sign a key. 2. store a comment in my secret ring that is captured each time I sign a key. Thus I could store the "reason/justification" for the signature to jog my memory. I know whose key's I've signed now, but as the number gets bigger, then I'll need a memory aid. I suggest the secret ring, as I share my public ring, and don't think that why I chose to sign a key should be generally available. If this were supported, you could then send me a msg asking "why did you sign John Doe's key?" You would have to compare my answer to my published policy and make your own judgement as to whether I follow it. I could keep track of this manually, and should. But PGP already requires me to have a lot of files arround.
