I signed up for the Do-It-Yourself Geo Apps MOOC in June, for the session running from July 20 to August 16 2016 and received an email which stated "We’ll send you instructions on how to log in to the course on July 20th". It is now 21st and I still have not received anything! From looking at a question that was posted yesterday it looks like other people have received log in instructions. Why have I not received anything? Is this something that has happened to other people?
