Hi. I have just installed Zen Cart 1.3.9 as an eCommerce solution to sell subscriptions to view articles restricted to subscribers only. There are articles which anyone can view also. I want to use the zen cart to sell the subscriptions. Upon completion of the sale, I want the email to include a link to activate the subscription, at which point I can add their information to a custom 'subscribers' database. How and what do I need to change to do this. There will eventually be other products which are not subscriptions, and will not need an activation link. Any tips to point me to the right area to change are greatly appreciated. I had this process more or less worked out without Zen Cart, but needed the shopping cart functionality and features it includes.
