If you can't find the answer to your question in our Help Center, you can contact the edX Learner Support team through our Contact Us form.
There's a link to the Contact Us form on the bottom of any page on the main edx.org site where you browse courses.
We don't have live support available at this time, as we are working across timezones to efficiently research and respond to all inquiries via email as quickly as possible.
If you have a question about an assignment in a course, or want to ask your instructor a question, post in the course discussion forum.
