How do you add additional comments?

Click on the "pencil" icon below your question when you post it; there is a "pull-down box" that gives you the option of editing the question or adding details, etc. Hope this helps.

You can only add comments to resolved questions. Then you can comment on the answers and best answer.

Go back to your question, and there's a button you can press that says "additional comments", or something along those lines.

just like the first one said

Only you can when the question is resolved.

carefully
