TvTorrentz.org (not to be confused with Tvtorrents.com) is currently open for signup. It’s a decent TV tracker with ~4000 members and 2300+ torrents. Currently there are around 150 spots available in this week’s open signup. Should be a useful tracker for new users as well as those who are missing their daily dose of TV Shows due to tv.torrents.ro being offline.
For signup URLs, tracker review, and more information, please refer to this post.
