Stackoverflow-like Q&A forum for my site
I am teaching a course and would like to let my students ask and answer questions related to the course material. I am looking for an Q&A forum similar to stackoverflow.com, namely:
- Everyone can ask questions and write answers;
- There is a reputation system - users gain reputation by asking good questions and getting good answers.
Is there an application with these features, that I can easily install on my Ubuntu droplet?
