Allow moderators to comment on cases
it would be good if we could also comment in the admin interface (with our username) and resolve cases. For example several people report internet blocking. In such cases we can recommend valuable information. Similarly if cases are resolved it is important to highlight this information. Such comments should be visually highlighted. Additionally, the users which submitted the case (as well as other people that commented on it or confirmed the case by clicking "me too") should be notified about the admin comment.
