If you’ve taken a look at the aMember solution (amember.com) and wish to use that, we’ve built an extension that we will be uploading to Magento Connect shortly. aMember facilitates a ton of membership/subscription functionality and also includes build in payment systems, coupons with statistics and a nice affiliate system.
Works with Magento 188.8.131.52 and above as well as the last major release of aMember and above.
Our extension is bi-directional. It includes:
Login at aMember -> user logged into Magento
Login at Magento -> user logged into aMember
Logout at aMember -> user logged out from Magento
Logout at Magento -> user logged out from aMember
The extension does quite a few auxiliary things such as password changes in both systems and updating the aMember templates to allow for and show email address as the login, etc.
The extension is upgradable and does not modify any core files. . If you’re interested, please direct message us and we’ll be glad to talk! We also take care of installation for free if you would like.
