Thanks Stephen, now some more questions (you knew this was going to happen...)

OpenPGP is for incomming email signing ?
OpenGPG is for outgoing email signing ?

Am I right, or do I have something mixed up?

Also, the above is not for encryption, right? Because the email I get with these messages, can be read (but just have the message above them), so it can't be an encrypted email. So, "signing" an email just ensures who the sender is, and that "they" sent it, correct?

Considering how much the trouble, as seen above, to get "signing" working with email, and the fact that I don't have anyone I would "need" this for, nor would they care if I did or not, and that the email I am getting that has this, is coming from ALSA email newsgroup, I think its a moot issue to get it working. I just thought, by the message that pops up in the email, it was something serious that I am missing, and by the wording, something that "should" be running, or something is seriously going to go wrong, kinda thing.

Thanks again for the help Stephen,
Ms. Cuddles
