If you report a post, how do you know it's progressing, whether it's resolved, or not? Mods can see your mail. Don't you deserve the right to even know the reason for acting on the report (if action took place)?
Also, how long does it take to take action on a post? (Any max duration?)
Based on the design of the forum as it is now, you can't know the status of your reported posts but you can have idea of the mod or the possible mods that will attend to the reports since most of the boards have moderators assigned to them that handles such issues. Actually one may think it's right for individuals to know the status or outcome of posts they report but I think implementing such will require a whole lot of coding and designing, hence I don't know if the forum admin would want to invest resources to that.
