No category is without an editor.
Best advice to get listed is:
1) Have a site with unique and valuable content that adds value to the category
2) Find the one best category
3) Write a guideline compliant title and description
4) Submit ONCE to that ONE category
5) After one month, ask at
http://www.resource-zone.com if the site is waiting (tech problems do happen) - PLEASE read the guidelines there first.
6) Forget about it - there is nothing more you can do; spend your time on other forms of promotion; don't obsess over DMOZ.
