I just submitted a site to DMOZ and this is the response that I received back: Submit a Site to the Open Directory Sorry, we could not determine your IP address for this submission. This may be because your browser or ISP has cached the previous page. There is no need to resubmit; your site is in a holding area. Once we've verified that it is not spam, we'll add it to the unreviewed sites in the category you've requested. We apologise for the inconvenience. Please go back in your browser if you need to resubmit the form.
How do I know if I need to resubmit? Should I resubmit or not?
Your site is in a "holding area" and will be manually reviewed and sorted back out to the most useful looking category, by some industrious editor or other that hangs around this pool like a waiting shark.
No need to worry. Don't keep on re-submitting as that just makes more work for editors (and eventually gets treated as spam if it continues).
