The First Season is available on Fansub and even listed on AnimeSuki. Follow the link.
The Second Season is licensed and so you won't find it here -- ever -- you that you are not allowed to ask for licensed anime (in case you don't know). I think the same goes for the movies.
As for the third series... it isn't available on fansub yet so I don't think you will find it anywhere.
All this information is available on the site and forum already... If we don't list a show; chances are you are wasting your time and ours asking for it. So, before you think about posting similar questions, can I ask that you read the torrent listings we provide ~ You would have saved all the time it took to make those two threads.
