One tip – when you have to sign up to edX to do the courses you will be presented with an option to ‘connect with Microsoft account’ along with options to connect with Facebook and Google too. I normally shy away from explicitly connecting accounts like this but decided, this once, to use the MS connect facility to connect to my hotmail account. This does NOT work (well not for hotmail accounts). Worse, it appeared to work for 24 hours before it stopped and causing much confusion and gnashing of teeth. Apparently, it will work for Office365 type accounts but not ‘consumer’ grade Microsoft ones.
Wish I’d followed my usual advice when faced with another new web registration – a deep breath to calm the rising frustration, open Enpass and add another login.
