You can also have your web page in a directory called 'WWW' on turing.
In this case your URL will be
http://www-linguistics.stanford.edu/~username/
assuming the main page is in a file called index.html.
This has the disadvantage that you'll have to fit all your files into
your turing quota, and if you're using many images and making
available many ps files they can take up a lot of space.
You can use the program latex2html to convert
latex documents into HTML so that you can put them in your web pages.
Pictures (trees etc.) will be automatically made into gif files and
integrated with the resulting pages.
Use weblint to check the syntax of your html
pages.
If you write a lot of web pages you may want to consider using the
html-mode for emacs - it saves a lot of time. See help html-mode.
