How does the comment system and comments work?
I have not been able to figure out how to add comments to questions/answers on stackoverflow.
For example, I wanted to comment on this answer to a question but there is no way to add a comment that I can see. I ended up adding another answer that corrects/clarifies the first answer. That doesn't seem like the best thing to do.
After adding the answer, I can see that there is an "add comment" link below my answer only. But nowhere else on any other question or answer do I get an "add comment" option.
