How Does One Recommend/Suggest New Category?

The ODP is lacking a category for which there is a significant and growing demand for websites containing information on the subject. For example, Wikipedia has a very extensive and informative page, created and expanded by several individuals, with links to numerous other well-informed websites on the same subject. But there's no category (nor anything related) in the ODP.

How does one go about recommending/suggesting the creation of a new category?

Thanks in advance...

The ODP generally doesn't create categories for each Wikipedia article. And categories for which someone demands websites, are even less promising (since vanity-affiliate-doorway-site spammers follow search terms so closely.)

What we do is create categories for the sites that we actually find. You can help us find sites of a particular kind, of course: if we even see something to suspect a pattern of good sites, we may be inspired to go create a category.

Another way is to offer to edit a category (and mention in your 'reasons' that you actually want to edit a subcategory comprising such-and-such listings and kinds of listings.) That's how I started editing.

Another is to generate a 'sui generis' site that all by itself cries out to have a category built around its core topic.

As always, all of this is volunteer work; and each volunteer works on his own priorities. So there's no way to impose an obligation or responsibility on someone else to edit a subject that interests you -- nothing works that way. So waiting on other volunteers can be frustrating if you can't put your impatience aside and focus on the value that YOU'RE proposing to contribute.
