Ask How do you set up affiliate marketing for a membership site?

[SuperAffiliateX]

I want to grow my membership site and someone suggested affiliate marketing. I don't know where to start when it comes to set up the affiliate program. Do I need special software? How do I find affiliates who will promote my site? I also worry about tracking sales and paying commissions. I want to make sure it's set up the right way from the start. Can anyone share the best way to set up affiliate marketing for a membership site?
