Changed my site URL

hi, i recently submitted my site www.angelfire.com/bug/little_mi/home.html to http://dmoz.org/Shopping/Clothing/Casual/Caps_and_Hats/
however, i've just updated it and the URL has changed to http://www.angelfire.com/bug/little_mi/index.htm
because the site hasn't been listed i can't just change the URL but if the moderator looks at the old one they won't find anything.
I know this is a real pain of me and i'm very sorry but i wasn't sure who i should tell or what i should do about it.
Thanks
Little Mi

Submit the new URL, put a note to the editor that [this replaces the old URL xxx which has changed.]

When the editor is clearing out duplicates, they should check -- if the new URL works and the old doesn't, it'll be easy enough to know which of the two to delete.
