Tweet

I signed up to pickjack at the beginning when it was lauched then i stopped and now am back on it again but i can see that somethings have changed. i no a lot of users of mylot also use pickjack so i thought il ask here ok the questions: 1) how many points make how much money? 2) how often do they pay? 3) does being in the lead help in anyway? Thanks in ad!
