Well, I didn't have problems commenting; I know it's important and can't be overemphasized. While quality comments can often be longer, it shouldn't be a strict rule; because meaningful, concise feedback is valuable too.

I prefer not to include our comments link in our posts because I want to keep the focus on the main topic for clarity and purpose. Additionally, it can be demanding to keep adding the links later on.

While I don't have issues with the rules of the chosen communities, I think it's important to consider multilingual communities to ensure inclusivity. Language barriers can prevent some people from participating, so I believe it's important to address this. However, I understand that the final decision is up to you since it's your course.
