Open Source and Digital Copy Torrent Tracker

I'm not sure if this is the right section of the forums, if so feel free to move me. Also, I know this can be a potentially sensitive topic so I welcome some mod intervention if needed.

I'm part of a private tracker that's been great for old obscure anime, freeware / abandonware games, and such. Unfortunately the site is slowly dying so I'm trying to find another back-up option.

Anyone have a site that they like and trust?
