I have a listing that is out of date for one of my websites, but since then I have forwarded that url to a new site, which I also submitted to Dmoz without thinking of my previous listing. The new listing isn't listed yet, so I would like to take off my old url and put on the new one. Can I do that? I never submitted the original listing, someone else did that to be nice so I don't have any information other than the url. Thank you.
