Well, the UID is what other people sign. Suppose by a wonderful coincidence
my name is Barack Obama. To prevent confusion, I create this UID
"Barack Obama (NOT the US president) <barack at is-my.name>"
People sign this. They have seen my birth certificate... erm... I mean
passport :), and the comment is quite helpful. Now I change the comment. I
don't think by now I need to spell it out anymore, but here goes:
"Barack Obama (US president) <barack at is-my.name>"
People might not be so happy they signed this UID.
But you can simply create a new UID (command adduid from --edit-key) and
delete the old UID (command deluid). That, as you say, doesn't help when
it's on a keyserver as you can't delete data from a key on a keyserver.
Likewise, people who already have a copy of your key and import your "new"
key will still have the old UID as well(!).
When other people already have your key, revoking the UID (command revuid
from --edit-key) is the standard way, if you think it's worth it for a
changed comment. As people who sign your key sign an UID, you also "lose"
all signatures when you revoke the signed UID.
I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
My key is available at http://wwwhome.cs.utwente.nl/~lebbing/pubkey.txt
