Step two of our upgrade path is more-or-less complete. I've added navigation tabs in place of the chaotic list of links in the header. I've only tested them heavily in Galeon & Mozilla, but verified they also work in Konqueror (which seems to be quite IE-like). Opera, on the other hand, doesn't like my CSS tabs at all, ignoring them and just displaying a list... For now I suggest Opera users login and select a different theme.

I implemented my new 'taxnav module' on top of Drupal 4.3, so I've also had to upgrade the site. For the most part, I hope this upgrade will be transparent... But please let me know of any regressions. BTW: for those that prefer to see all site content, try this link.
