Mouse over the pencil pic (under your question) & from the drop down menu choose Add Details.

Answer 2

When yob choose a best answer you can add a comment of two or three sentences.
You can also used the "edit question" button (the right most one under the question) to add more details, some of the new details can be a response to earlier answers.
Finally you can click on the little avatar picture and get a person's profile. From this you can e-mail them, instant message them or even look at their blog at Yahoo360. (Not everybody enables this function).
I hope this helps!
