a handful no of sub categories for the categoy.

Good luck with your directory - very nice looking . So far I know you do the design yourself.

Do you provide desiging service ?

Probably a good idea to put the number of listings you have on each sub-category (example: - Directories | Ask Directory ), so people don’t go visit empty categories. I hat to visit empty categories. Another option is to not show the category unless you have listings, the category could be indexed using a sitemap page.

Your directory looks very nice.
