As much as it pains me to pass this on, we've had multiple requests for threaded comments and replies to forums and blogs. Igloo is used in our community for study groups, where students are expected to reply to an instructor's forum or blog post, then respond directly to each other. In this situation, it's incredibly difficult to follow a response using flat discussion and @ mentions. Is it possible to add a feature where we have the option of turning on threaded comments/replies for a single space?
