If I went with a Free membership, my concern is that displaying the oto after initial signup would not give subscribers the chance to view the content and make a decision to buy based on previous experience. So low conversions, BUT, I would be building a list with a chance to upsell later. The free members would automatically become affiliates.
If I went with a Paid membership and OTO, I could provide a mini-course as an optin, provide the same content as the free membership, but I wouldn't have any of the free members becoming affiliates. The only way to promote would be to become a paid member.
Can anyone provide some recommendations as to which method would be better?
