Be certain that a site meets the criteria not just that there is a chance. In most categories now, "a chance", when that is your assessment, almost certainly means no chance in our assessment. Be objective, and hard on your own sites before suggesting them. In checking for your site I rid that category of about 100 pure rubbish suggestions. You can imagine how much time that wasted when I could have been listing schools and hospitals and community groups and garden centres and people with highly original products to sell that no-one else has yet offered on the Internet.
I have a site myself I am intensely proud of, unique content researched and written myself, nothing even close (in my opinion) in terms of quality (which is why I thought it needed to be done) and which, according to the site stats, must be being used as a Home page on a dozen or so browsers. Yet I still don't think it is good enough for DMOZ. One day maybe.
