This is just because I know alot of people who dont know when and sometimes where anime is released.
The Following sites will tell you the time of release, the sub group who released it and give you the torrent link to download.
Animesuki - This Site is best layed out however it does not show licensed anime as a rule.
Tokyotosho - This site is not layed out as well, but it does show licensed anime aswell as Raw, Manga, Music, AMV releases.
Baka-updates - This site is best layed out. But it does not always have the torrent links. It also has alot of Info on Sub-Groups(irc channel, website)
These should help people waiting on new releases. People can add more if they wish. Hmm maybe this should be a guide..well whatever.
