Use short descriptive file names (perhaps relevant to the page title).
File names should be all lower-case, with only alphanumeric characters and
hyphens. Don't use an underscore in the file name; it will not be visible in a
link. Also, don't use a period (.) in the file name except when it immediately
precedes html (for example, create-file.html).
File names should be no longer than 8-12 characters before the .html.
File names must not include spaces.
File names must end with .html (not .htm).
E-mail addresses should be all lower-case
