So here's what I'll tell you:
First, apply at 5-10 networks and get accepted. (If you are wondering how to get accepted ... SEARCH )
Second, read through the networks FAQ sections. You will find lots of information there that will answer most of your questions or at least steer you in the right direction. MarketLeverage for example, they have video tutorials explaining simple things like CTR, estimating your EPC and how to use sub id's. (these are sure to help most noob's)
Third, when you have a question not found after reading through them, then read through Every post on this forum, wicked fire and the cashtactics blog.
Finally, when you still have questions after all of that leg work, then feel free to post here and I and several others will be more than glad to help you out.
This not only shows you are willing to put in the work to be successful with cpa marketing, but more importantly that you have what it takes. (justify this for yourself)
One thing that has helped me to become a successful affiliate marketer is the understanding and ability of figuring things out for myself, and Not simply expecting a silver platter handed to me.
I hope this helps you out and will clear up some clutter on this forum so we can look forward to more quality threads and posts.
