Hi guys, there is something I don't quite understand yet. I am now on the website of OGads and CPAgrip. I want to have my followers enter their e-mail address, so they can "participate" in an giveaway. Would the best way to do this be creating a content locker? I do not see any other option, but I am not giving them "content", just a participation. Secondly, on both the websites you can choose some domain names to host(?) your content locker on. I imagine this is bad, since allot of people are using these domain names for their links? Or is it safe to use them. Thanks in advance! If anyone wants to help me out with CPA, that would be great!
