Alright that's a good answer but aren't people just confirming the email address belongs to a known signer when they sign a key? Does it really matter what the UID comment is? I think it may be going a bit too far to say the UID is guaranteed. > But you can simply create a new UID (command adduid from --edit-key) and > delete the old UID (command deluid).

Do I have to do anything with the keys when adding a UID and deleting the old one?

My question is on a situation I didn't add the comment by mistake when I created the key and now I'd like to be able to add a comment. The key isn't signed etc. Thanks.
