The Submission Process:

Listings within the directory are sorted through two different methods.

The first method is via the topical category structure and the second is via a regional category structure.

What this means to you when your submitting a site for consideration is that you will need to select the most appropriate regional category and the most appropriate topical category.  If you feel a category should be added you can suggest it on the submission page.

On each page it will ask you right above the categories if you want to place your listing in the current category.

This creates a much more user friendly structure for visitors who are looking for resources because it allows them to search based on both region and topic.
