I stumbled across Keyoxide today. I gave it a shot, created and uploaded an ASP [1]. Now I have my own profile [2] that verifies some of my identities, neat! Adding my mail throws an error message though. I use WKD to publish my OpenPGP key [3]. I learned that my mail address is therefore already discovered by keyoxide.org [4], can't be used twice as it seems.
