Clients for AUTHINFO access/440 error on post

[Christopher P. Lindsey]

I'm trying to put together some documentation listing news clients that
work with password-based NNTP access with tips on configuring those
clients.

Am I replicating anyone's work?  Does anyone have any existing client
configurations that they're willing to contribute privately (off-list)?

This is borne of an hour-long frustration with Mozilla.  They have a great
graphical interface, but it doesn't recognize public read access and
restricted post access.  And that brings me to a second question...
