Added - I THINK that you are looking at this site like threads for FaceBook. It's not like that. You write a question, people answer, and you can add to or comment on a general basis in the SWH. Does this help?
Original:
I have lots of blonde moments. Don't let it bother you!
When you go back to your question, it tells you that you can post a "So What Happened". That's where you comment.
Hope this helps,
