I have 4 different websites which have been submitted to DMOZ 4 times each. I have given up trying as I have NEVER had a reply back on ANY of them, in spite of the fact that one site is deemed by scientists, academics and farm organisations worldwide to be the most authorative Global site on it's subject matter. Even Google gives it Page Rank 5. [ http://www.MolecularFarming.com ]
My other sites are shopping type directories specifically for Plus Sizes, and contain limited amounts of unique content, but at least if I had had at least ONE reply saying so it wouldn't be sooooo bad.
