Chain of Command

In May I became an editor at a university math website. My main job is send visitor math questions out to the appropriate group of volunteers and then post the solutions on the website. There is this one volunteer who insists on sending her responses to the other editor. Since it has been assigned to me, he has to go out of his way to forward the responses onto me. It isn't a matter of her not knowing what to do, she is willfully doing it. The reason I was hired was to decrease the other editors work load and get the responses on the website quicker -- she is not helping the situation.
