Like I mentioned in the discussion topic (
http://www.ptcbox.me/forum/YaBB.pl?num=1378894877/0#0), YouGetProfit is a PTC site from Twickerz group featuring a revenue sharing program. Lots of details are still a bit unclear, but it seems a promising program worth building a downline for.
Besides the earnings from PTC clicks and share earnings, there are 100% referral comissions for clicks, 10% for upgrades, 6% for ad purchasing in the level-1 downline and 4% for the level-2 downline.
