It's great advice Mitch, the only problem is that DMOZ is extremely slow at adding any listings.  Especially if the category is looking for a volunteer to edit it (you can see that at the bottom of any category).

FYI DMOZ is hosted (supported) by Netscape/AOL and about a year ago the server blew up (and there was not an easily accesible backup!).  It took months for the listings to be restored and since then getting added takes longer and longer, especially if you don't give a good description, i.e., make sure to use their advice in giving descriptions of your website, submit it to the proper category, and hopefully a category that has an editor looking over it. 

There are some listings that I have currently submitted that are over 2 months old. 

At one time I was an editor and had listings approved in days . . . that is no longer the case since there aren't enough editors and submissions are growing exponentially.  It is all done by humans.

Agreed.
