Logged-in users vote on the quality of a release. Use Report Torrent for torrents that are fake, mislabelled or malicious, so moderators can remove them.
Yes: the API page has a ready-made indexer definition and setup guide.
Use the sun/moon switch in the bar under the menu. The choice is kept in your browser.
Use the contact form for requests, bug reports, feature requests and help.
