Interesting idea. I tried this, and still no workie. I think wordpress needs the trailing slash. I think the problem is this:
domain.com/page-title-here/ is actually
domain.com/index.php?id=1234 that's being re-written via mod_rewrite to the "pretty" form. so in a way these custom pages are something like:
firstname.lastname@example.org... etc which of course is silly and wouldn't work.
i think the only solution is some custom mod_rewrite magic.
any one else with ideas? i'd like be able to update these titles/urls without editing .htaccess...
