At the bottom of the description of the resource, add a link that says, "Discuss in the Forums!", which should point to an existing discussion of that resource. If no forum entry exists for that resource, the link will open up the Post a message page for the first entry.
Question is, where in the forums should these entries appear. It seems that discussions about existing and announced Logos resources are found in both Logos 4 and General forums. Perhaps Logos should create another forum called Existing/Announced Products.
