I have used adster for a long time. I was not making any money frm it, just too less click rates. The only best ting of them was their online support. But who wants if they dont give high pay rates. Frnds be careful, unless u get a lot if US and Canadian traffic dont use it
well, i'm about to "receive" their first checks, lets see if they pay me, you can find some cool ad networks, on my signature link, they have all the specifications and my personal review
