Please let me clear up a few misconceptions.
We don't care about SEO, we're a directory.
We don't advise people how to design their websites; that's their responsibility.
You can't 'get' a site published in ODP. All you can do is suggest that we list it.
You (and for that matter, we) can't contol the elapsed time to review.
No site is guaranteed a listing.
