For training I'm working with a standalone CQ5-Server. Right now I'm working with "Overlaying Comments" -> "Create a Comments Page". The exercise shows how to adapt a modified comments-component from the "Social Collaboration"-componentGroup at path "/libs/social". In my environment this path isn't there. So I exported the path from another CQ5-Server and imported it in mine. But when invoking WCM, the sidekick (design mode) does not offer the "Social Collaboration" componentGroup.
