Have you considered running a Massive Open Online Course or as it's commonly called, a MOOC? I'v been involved in MOOCs since 2007/2008. I started organizing my own MOOCs in 2013 with the first Moodle MOOC on WizIQ in June 2013 and the second one in October 2013. Organizing and conducting MOOCs on WizIQ is easy and rewarding for everyone involved. So much so, that I decided to have 3 Moodle MOOCs a year, a Second Life MOOC in April and a Healthy Living MOOC in September.
