This happened to me a few days ago (as a vendor). I got a dedicated TOR system and moved everything off my old system but forgot to get my private key before I destroyed my old drive... so here I am with orders pouring in using my old public key with no way to access it... I did send my new public key to the buyers who used the old one and I got most resolved but a few kept giving me problems. I am in no way against using privnote as it can be accessed via TOR so I don't know why people have such a problem with it. A little paranoia is a good and necessary thing in this business but when the axe drops it is not the buyers who are going to be in the paper...TJ
