I was hoping there would be a magic answer to this...... I am having trouble getting accepted as well
The magic answer is that DMOZ listings are worthless, update your SEO notions, and have success in the SERPs.
Sorry no magic answer, submit and forget, don't re-submit and one day when an editor volunteers to sort that area and chooses to use the suggestions pool, you will get a review and if it is acceptable under our guidelines will be accepted, providing you sent it to the right category, if not it will be moved but may delay the process.
