Trent Buck reports failures with authentication and editing using text-mode browsers such as emacs-w3m at a page like http://www.mechanicalcat.net/tech/roundup/wiki/MessagesAsMbox . I can reproduce it with emacs 23.0.60.1, w3m-el 1.4.4, w3m 0.5.2, even with cookies enabled. The login and edit seem to succeed but there is no effect on the page.
