If you follow these directions and still have trouble setting up a web page or posting a file to it, please see the MFCF Unix Consultants (MC3017) M-F 9-5 and they'll be happy to help.
Please see MFCF's FAQ on Creating your own web pages for details how to setup your own website, and particularly How to Put a PDF on the WWW
Since the course newsgroup (uw.cs.cs492) doesn't allow binary attachments, please post PDFs as a web page, then link to them from your newsgroup posting. If you want to post files elsewhere on-line, feel free, just make sure the file will remain accessible for the entire term.
