How does the main page get updated?
The best way to update the main page is to send email to the website administrators.
The main page can be updated by key personnel who are administrators of the workgroup that corresponds to the site.
To become an administrator for the workgroup, send email to: www@site(www at chess eecs berkeley edu or www at gigascale org)
If you are a member of the administrator workgroup, then there will be a 'CVS update' link at the bottom of the page that will update the page and a 'Help' link that discusses how to check out the website.
