Thanks so much for all the tips on forum/mailing list integration. I am still exploring the options with the client. Now I have another puzzle. I am using Organic Groups for a teaching situation. Makes sense. People who have paid for the class will get access to the class manage by OG. But I would like to create a unique home page for the class and not just a list of recent posts to the group. I've read lots of threads on drupal.org, but haven't found a good solution. Ideally, what should happen would be that when a registered student logs in they are directed to this landing page which serves as a portal for the group/class.
