Mistake in submission - what to do?

I now understand (about 24 hours too late) the DMOZ policy on a site with a main domain and seperate domains for each of the product groups. I just submitted urls for two of the product groups (the main site was submitted 4 weeks ago - status not known). What is the best thing to do to get the two submission made yesterday cancelled?

If you drop me a private message with all three URLS (with details of the 2 you want cancelling and which category you submitted to), I'll try and work something out for you.
