Question about Lesson 4 (not mini-lesson)

First, is this the right place to ask a question about a specific course, or is there some place that I haven't found that allows me to ask a question within the lesson itself?

My question is this: the lesson says "No te preocupes" for don't worry. I can't figure out why it has the "es" ending for an "ar" reflexive verb (preocuparse). Is this getting into the subjunctive?
