Is there any forum functionality inside of ERPN?

Dear Sirs. I’m just starting to consider ERPN to camp there a free educational project.
We have a lot of a tutor-a student discussion during educational process (can be very long threads). I can’t find any functionality that can suit to that discussion. Don’t you have any idea?

A little bit more details. We have several questions inside one task. Answers to them show how well a student worked material. Each answer can be commented by a tutor. Then each comment can be commented by the student because he or she needs to defend own view. And then back and forth - the discussion can go for weeks. Therefore i need to find a functionality that survive in this long thread and will be user-friendly. At the moment have no idea what function of ERPN can i use for that.
Really appreciate any suggestion! Have a nice weekend.

Hello,

Discussion board is already on a wishlist in the ERPNext Schools module. Wil be great if you can create a Github Issue for your suggestion. If we get good traction for your suggestion, we will consider adding it in the milestone.

We have some work LMS (learning management system), but it needs to be completed. (check slide no. 73)
