Actually there is an article on SEO MOZ & I think its about the size of it. I cant past the link but will put part of it in -
Applying to become a DMOZ editor is easy. Getting accepted is a little bit harder, but definitely doable. The first step is to find the category that best describes your website. At the bottom of that category you will see a link that says "Volunteer to edit this category." This will take you to the next page which gives you tips and advice on applying to become an editor. Read this page! At the bottom of the page click on the button that says "Proceed" to go to the actual application.
DMOZ will only approve you to edit one category at a time. After you become an editor, you can apply to edit other categories. Whether or not you get accepted to edit other categories depends on your body of work up until that time as an editor. That is why it is a good idea, even after you are approved as an editor, to carefully follow the editorial guidelines on websites you approve to be in the directory. If you have multiple websites waiting to be approved by DMOZ editors, I recommend applying to edit in the category for which your most important site is waiting. Do a good job editing in that category and it will be easy for you to be approved to edit other categories.
It is best to start with a smaller category. Usually less than 100 listings in a category will give you an excellent chance of being accepted.
The actual application is where you need to be careful and do a little homework. Here you will be asked to provide the usual (your name, username, password, email address, etc.).
Further down the application page you will find four boxes to input information. Doing a good job filling out these four boxes is critical to your application. As you fill them out, make sure your punctuation, grammar, and spelling are all correct.
