I've built a Magento extension that quickly facilitates solid integration between Magento and aMember. The extension works with Magento 1.4.1.0 and above as well as aMember 3.1.8 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 Magento or aMember core files. . If you’re interested, please direct message me and I’ll be glad to talk! We also take care of installation for free if you would like.
