Hi Greg, This is something I am definitely going to implement but we had a set back with the whole PHP4 and PHP5 server issues so we decided to work on updating the whole codebase so it works seamlessly on both PHP4 and PHP5. We also added the option so you can now integrate the eMember users with your wordpress user database so when a member signs up in eMember an user account is also created in the core wordpress user database so the login credentials can be shared (this feature can be turned on or off). This option resulted a lot of additional work. Anyway, hopefully we should be able to implement the email address getting feature soon.
At the moment renewals are handled by subscription payments. So for example if you want to create a membership where the members have to pay “x” amount of money per month or year to stay subscribed then all you have to do is create a “Membership Level” and set the subscription duration to “Never Expire”.
Now configure a Subscription button in eStore and hook it to this membership level (http://www.tipsandtricks-hq.com/wordpress-membership/?p=60)
Once they make a payment using this subscription button they will become a member but they can’t cancel this subscription in order to stay a member cause as soon as they unsubscribe PayPal will notify the eStore plugin and it will automatically deactivate the membership for this member.
This way the recurring payments and subscriptions are automatically handled for you and you don’t have to worry about sending notification to your members and stuff. Does this make sense?
