Oh, good. I've been hoping to be able to get some advice from gnus
users. I want to figure out how to get gnus support for viewing
encrypted messages, etc.

Do you happen to know some good documentation for how to get started
with gnus for reading mail? I'd be happy even with the bare minimum to
just get gnus to view one single message from out of my mail
store. (Which is something I tried to figure out from the gnus manual,
but I neve succeeded.)
