[thelist] need a bit of htaccess help

[Jon Hughes]

I have the following:

Options +FollowSymLinks 
RewriteEngine on 

DirectoryIndex index.htm index.html Index.htm Index.html index.php

RewriteRule ^notes/$ /notes/index.php
RewriteRule ^/notes$ /notes/index.php

RewriteRule ^([^\.\?]+)(\?.*)?$ $1.php

(EOF)

This works for "http://www.phazm.com/notes/" but does NOT work for
"http://www.phazm.com/notes" (no trailing slash)

Does anyone know what I must modify to make that work?

Thank you,

 - Jon
