Whenever possible, make relative links for links from
your project Web pages to other Web pages that are in
that same project. This will make it possible to move your
project to another Domain name.
We strongly suggest using all lower case letters
because people make fewer mistakes with it.
Also name your files with images, sounds, etc., with
names that will help you remember what is in them.
