I would also check with your tracker to make sure you can share. you might need to create a new torrent file. In other words; if you get the file from tracker A and the torrent is file_releaseG, upload it to tracker B with a different name such as file_releaseF and give proper thanks to the OG uploader. That is typically what I do. I hope it helps, but you should always check the FAQ and rules for the trackers to be safe.
