Three options:
1) Put a shrine up on an east facing wall at sunrise - light a candle and worship at the shrine 3x a day .... also it apparently helps your site if you put a Google one next to the DMOZ one as well :-)

2)
a) Have a site that really would add value to the category you want to submit to. Make the content good and unique.
b) Write a guideline compliant title and description
c) Submit ONCE to the ONE best category
d) After a month, check at www.resource-zone.com (follow the forum rules) to see status (tech problems do happen occasionaly)
e) Forget about it as there is nothing more you can do.

3) Become an editor and become part of the solution.
