Do you have any existing functionality that allows for integration with WPMUDev's e-Newsletter plugin? I would like to be able to automatically submit a new registrant to a group within this functionality. I know that you have existing email integration, but I was looking for a way to create a free/low-cost integrated solution for my clients.
Here is the plugin i reference: http://premium.wpmudev.org/project/e-newsletter/
Thanks.
