I for one would love to see how this course could transition into become a community. Apart from some of the steps you detail in your “Success in a MOOC” animation, other things I’ve seen lead to being an inclusive and welcoming space for newcomers are:
an initial designated place to go or structure to plug into to help ground them in the community and get comfortable with its norms
a recognition or welcome as a means to acknowledge that they have entered and exist
introductions or the ability to connect and “know” others
a place to ask questions, express concerns, vent and openness and transparency in the community to these processes
multiple ways to engage and the opportunity to exit and return
