I would like to direct your attention to
MV Group.
They host torrents (decently seeded ones at that) of a wide assortment of documentaries. From the BBC and David Attenborough's stuff to other nature docs, History Channel, PBS, Discovery, National Geographic as well as independent releases. Now maybe it's just my lack of a functioning television talking, but that's certainly of interest to me. I've downloaded the entire Walking With Beasts series, plus two other films (Baraka and Chronos) in about...five days or so. For one thing, school could benefit immensly from having a readily available source for a ton of top notch documentaries.
Given that they're hosting educational torrents to enrich the mind, which for the most part are freely available on TV anyway, and not eating babies, I would ask the admins to leave the link up. Pretty please.
