I dont know if you still need an answer but from what i saw you need to have at least 400 views (i dont remember if that was daily or monthly) But i heard mostly bad things about them, but i would do research on them.
@BeautyByCat Thanks. I e-mailed them and they told me you need 1,000 views for 3 months than you can apply to them. I've not ben with a network in a while. I know a lot of them have issues. Seems now a days you should join them if your channel is big and that we they can help with the channel. I think i'm going to stay away from networks for the time being. Thanks again for replying back! have a great day.
