Question-Answers when the students get stuck, need help?

Hi,

I’m wondering if any people here have thought about ways for the students to ask for help if they’re stuck on a homework problem? Or lets the students discuss-with-each-other / ask-questions-about their study material? (Via their mobile phone / laptop, as a complement to talking in person in the classroom)

Has anyone tried to find any such tools? To use together with Kolibri?

Or have you had thoughts about building this yourselves, as a part of Kolibri?

Or maybe not on the roadmap?
