Ithink that nCore is level 7, because I can find a lot of good things sutch as a music album or a software, and nowdays, It has legal torrents from Hungarian music bands.
AVLossLess is dead, got In to Libra net, I think that Torrent Day is level 4, because it has a good pretime, but I can't find a lot of things that I find on other trackers.
I think that Xider is level 1, because the members receive a lot of ads in pm, and the contents isn't good.
Gamer fan is dead, the owner of the site had a new page called Black core, it's a general tracker.
Insane is jump a level up, because the community is very good, it reached the 400 k peer, and it's a perfettibile tracker.
Sorry for my bad english, Torrentguru.
