Sorry if this is longwinded but I'm trying to add a recurring subscription option to site but want to prepare for future headaches. We have a good core following on a statewide news magazine site. For now I want to implement PayPal's Enhanced Recurring Payments option for subscriptions as I just found out users won't need a PayPal account. This will allow for monetary support and for the moment people won't have to hastle with signing up. But in the future I'd like to wall off some content and make membership mandatory for those areas. What would be the foreseeable problems at a later date if I implemented Solspace's User with PayPal recurring payments and using if statements to wall off content? Would I be able to transfer those people that initially sign up for a recurring subscription to the later setup, which would require membership? Or would I just have to tell people to cancel membership and re-sign up at that time?
BTW, I've researched Membrr, CartThrob, and Charge... and right now, the paypal option for the additional $20/month seems well worth it in light of some of the things i've heard about the other options. Nothing negative on Charge, but more trouble than I want to invest in right now.
