If you wanted to send very sensitive information to someone but didn't have that person's PGP key, you would search for it. To do so, you'd open PGPKeys, then get to the Server window.

I've decided to search for the PGP keys for anyone associated with WHOA. I know that all WHOA personnel have addresses on the haltabuse.org domain, so I entered "haltabuse.org" in the search field.

I found several WHOA staffers' keys on the server. I could select all of them or just one or a few, and then import them to my local keyring.
