i also wish there was some system that told you if you had ever downloaded a torrent before when clicking on it it
Here is the "trick" that I use (or try to use) for this.
Once I download a torrent, I go back to the GT.ru torrent page and rate it. I also thank the uploader.
Even if a year later I go to that torrent, the page shows me clearly that I had rated it before! :cheesy2:
I like this because I offload both the files and .torrents to DVD's randomly to keep my torrent pool to about 100 available (while my DVD library is vast).
