I got the torrents to work, but I would like to add multiple trackers. I know that there must be a blank line between each tracker, but I don't know how many trackers I can add.

I tested a lot of pubic trackers, and found 61 great ones. However, just to be sure my torrent will work, I want to use multiple trackers just in case one or more is not working, and also to increase the speed.
