We're starting the process of migrating to AEM, working with an implementation partner to get up and running. As a side project, we're trying to determine how to add the functionality of a typical discussion board/community forum to the new AEM site. At first we thought it would be easy, using the Adobe Communities product as an add-on to AEM. Unfortunately, it seems Adobe is no longer offering that product to new customers.
So... what are some viable options? Are the Adobe Communities features now built-in to AEM? Or is a third-party solution or custom development the only choice? Any advice or suggestion is greatly appreciated!
