Every community needs a leader. The internet is no different. A community website needs a core -- someone with a vision of what can be done, and a commitment to do it. If you have such a vision, then be about it: ODP editors will sympathize, and when the site begins to come together, it will be time to review for a listing.
What you have, so far, is an ideal.
Compare that to, say, the Christian Classics Ethereal Library,
http://ccel.org/ , where I'm a volunteer.
Down at the core, there's one man's vision (
http://ccel.org/info/vision.html ) including an ideal, a purpose, and a roadmap. It starts with his own work -- a few dozen books chosen, scanned, and published. He has a definite kind of content in mind, that had helped him but that he thought was hard to find. And he has definite ways in which other people can contribute.
Now THAT'S a "community" site! Oh, and NOW he has hundreds of thousands of pages of content. from other people.
You don't have any of that. You have an ideal, with very little content and (so far as the site shows) no particular kind of content in mind, nor a roadmap to get more -- either from yourself or from the community.
Making the site more visible won't change that.
What I would suggest (which is in fact what I do) is: rather than starting a community from nothing, participate in existing communities. Is there a kind of content that you've found useful, but that's not available on the net? Then MAKE it available -- and offer it to the net communities that you think might like it. (I've had a half-dozen e-texts gladly received by multiple sites. I could have had more, but I'm more interested in making texts available than in reposting existing ones.) If you identify material that nobody has and no current site wants, or a body of material that no current site will build, then will be plenty soon to start your own schismatic community. And by then you may be able to articulate the common concept or unifying ideal that would make your community distinct and unique. (My own material is just beginning to appear on the net this year. It is not yet listed in the ODP.)
But until then, be part of the communities that already exist. Share whatever benefits can be shared through them, while learning how they work. If you just want to contribute to the heavens or the earth on the net, you may not need your own website at all, let alone yet.
