well there is this
http://machinima.com/ wich though is not anime it's basically the org in relation to gaming videos Though it's kind of lacking I think but it's a solid start (though it's been around for many, at least 5+ years). also
http://ocremix.org/ is like the closest thing to the org community that I have found. Just not related to anime and music only, but they do catalog all of the songs involved (minus a few that get tossed out from time to time...). animeondvd.com used to be awesome, but they've sold out (I hardly recognize them any more ><), animenfo.com sort of catalogs but are even more elitist than us! if it's not up to their standards they toss it out. At least they've become a lot more user friendly the last few years. They do catalog 99% of all anime out there (though I do find the few VERY niche ones that are not listed...) what I refer to are just user reviews.
If you do not think so... you will DIE
