Is there a way to assign expired members to a special group expired. The idea is that active membership users after login will see all members content. And expired only the module with membership subscription?
That's available in the latest build of the extension (which I has not made the public release yet). If you want to have this feature, drop an email to tuanpn@joomdonation.com and I will send the version which has the feature for you (need to finish few other small features before releasing the new version)
