Ground Report Payment

Finally today I got my first payment from Ground Report.I signed up 4 months ago there but I never got paid until today.Well it's a new site so I think it's ok.What I got?They sent me 13$ at Paypal.What I did to get those money?I posted 5 articles at their website and every article was readed about 150 times by their users.The whole idea is users write articles and get money from the clicks on the Adsense ads.I think Ground Report gets 50% and you get the other 50%.Not bad huh?Anyway I hope things go better now.
