I receive many emails indicating that my GPG/PGP key has expired.
This is not true, about a year ago I altered its validity to extend beyond the original expiry date at some point on October 2005. I chose this way since it was possible (rather than creaging a completely new key).
Please re-downlaod the key from your favourite keyserver. If the problem persists, please tell me which keysever still gives you a key with an expiry date, so I can fix it by re-sending my current key to that keyserver.
Thanks for your cooperation.
