Hi olwen /images/icons/smile.gif
If you are applying to Regional categories, another very good way to find sites is by typing the zipcode of the Locality in the search box at Google, Yahoo, or other search engines or directories for the locality you wish to apply for. I found using a zipcode extremely helpful in finding additional sites to build a very small locality in Regional which only had around 12 listings to begin with. After using different SE's and directories, and trying the zipcode approach, the category is now up to around 120 sites, which is very good for a very small Regional locality.
Try applying again, check your application for errors, and be sure and give three good urls in your app. Don't give up if you've been rejected. As others have said, you may not be accepted on your first or second try, just continue to improve on your application and try again.
A bit more advice... start by applying for a small category. After you are accepted and have been with ODP for a while, you can then apply for another category you desire.
We would forward to seeing you at ODP!
