I found this thread today because like many other instructors, I want to be able to delete saved comments in rubrics. It seems like everyone agrees that this is a sensible thing to do (in what other online service is it impossible to delete your own comments?). I'm sorry to say I don't understand why this was sent to "cold storage" when the existing system is so obviously flawed. Your system requiring people to vote on things they would like changed is inadequate given that there's no way for someone to know that an idea has been proposed until they personally encounter the problem ... search for the answer ... and find their way to this discussion where it's too late to do anything about.
