Small typo in the link on the front page, to your homepage http://www.cse.unsw.edu/au/~neilb/index.html:
Requested URL: /au/~neilb/index.html Error Status: 404 Error notes: File does not exist: /import/albeniz/1/www/lib/html/au/~neilb/index.html Request Protocol: HTTP/1.0 Server Name: www.cse.unsw.edu Server Port: 80 Server Summary: Apache/1.3.34 Server at www.cse.unsw.edu Port 80
Curiously it works with or without the .au as both http://www.cse.unsw.edu/~neilb/index.html and http://www.cse.unsw.edu[.]au/~neilb/index.html work.
