I have looked everywhere, and we have not been given the ability to respond to mail from moderators. My concern is that the moderators are not always good at their job and may be abusing their powers. They do not seem to be able to keep the peace on a community based website, which is actually important, in my humble opinion, imputing their own rules and preference instead of making neutral rules that everyone can agree upon. My reason for needing to respond to mail is to reason with people, mainly because even if a comment is two years old, if it starts tension, it should be looked at, no matter how old it is.
