PHP can force everything to lower case for you during the ftp upload; is
that what you mean? Otherwise IMO it's a matter of just being consistant in
a way that's easy to remember & repeat. I don't like all lower case, so I
use a cap for the first letter of each term; e.g. ..MySite, OnThisPage,
etc.. Some people use underscores instead; that's a good design too and used
by many. Just pick a method, and stick to it. "There's always time to redo
it later" is not a good philosophy; do it right the first time.
