The action for the login form in the classic template
(..../html/page) has an action of "", which w3m seems
to interpret as a post to /, rendering much of the
system unusable in a text mode browser.

Also, in netscape-4.77, the css is interpreted poorly
and looks awful.

It would be cool in general if the html generated by
the server
would validate as valid xhtml or some such.

Logged In: YES

It should validate, but is not designed to be friendly to "ancient" browsers. 
If you wish to support Netscape 4.77 in your tracker, feel free to make local 
changes to the HTML or CSS (basically, remove any CSS that netscape 
doesn't cope with, and replace with horrid, horrid <font> tags and 
color/bgcolor tag attributes). 
 
I'm not familiar with w3m, but its behaviour is clearly broken and if you wish 
to work around it, then again please do so locally by insterting an 
appropriate action="" in the <form> tags.
