>Other national parks and game reserves have numerous "dmoz listed sites" about them. Have a look Yellowstone or Kruger!!
Sigh.
That's like a spammer saying, "you get 20 emails a day already. Why shouldn't I send you 20 more?"
Look, one organization, one topic -- WE call it one website.
They can put it on as many domains as they want, they can have as many different web developers working on it as they want; they can link all its pages together, so people can find all their content from one listing, or not. All that is under THEIR control.
The ODP will list one site. It is not the ODP's job to substitute for deliberately crippled website navigation.
Now, if Joe and Fred both, on their own initiative, want to make up websites about Kruger or Yellowstone, we'll consider listing both, even if Kruger and Yellowstone both already have official sites. And if two completely different federal agencies create sites on Yellowstone, we'll list them. But we don't regard that as the same thing at all.
One agency. One website. Just link it together yourself. Because the ODP won't do it for you.
