Lately, we've been introducing torrent trackers targeted at niche user segments. Here is another such tracker. SciFiTorrents is focused on, as the name says, science fiction content (Movies, Tv Shows , Docs, Books and more). The content is impressive - we even managed to find some rare sci-fi movies produced in the 1950s!
The good news is that they have opened registrations for all users at the moment. You may register a free account without an invitation code while the site stays in this mode.
Site Name: SciFiTorrents
Signup URL: http://www.scifitorrents.net/account-signup.php
Description: Includes a lot of SciFi content. But the tracker does track general 0day non SciFi content as well.
