Recently, both Quidscorner, and clicksvista were down on their daily click section. The onyl source you can make income from both sites are through sign up offers. I done a couple of sign up offers from both sites, but I still not getting any credit from them. So, I just wonder if any of you ever done any sign - up offers from both sites. Did they credit you?
