Lost or Compromised Keys
You don't have a nerdster.org or ONE-OF-US.NET account. If anything, you have an account with folks whove vouched for you.
Basic steps:
Use the phone so to replace your key
You can repace it as of the last statement it signed or further back in time if it's been compromised and was used to sign fraudulently.
Compel folks to vouch for (trust) your new key.
