I’ve been working on enabling rich media content features on the Commons. The initial venture allowed for video comments, but those comments were available for others to embed in their blog posts, instead of being solely viewable within the comment stream of the blog. Given that a number of our blogs are private, and would therefore infer a level of privacy within the comment stream, having those comments available to the entire network in the Add Existing Media panel was a security issue. For that reason I’ve turned off the video comments until we get that sorted. I hope to have it back up and running before the beginning of school, if not within the first week. Thanks for your understanding.
