Its a very lengthy process waiting to see if your website gets accepted in to DMOZ if at all, but i have a quick tip which seems to work when submitting to DMOZ.
Instead of navigating through the DMOZ directory looking for the category to which best suits your website, go to:
http://www.dmoz.org/Regional/
from here navigate to your country, state, town & so on to you get to the last section which could be the name of your street or town & then submit your website there
