So when you click on Answer to answer a question the answer form has a text box that states something like this:

Answer to: what color is the shy?

Replace "what color is the sky?" with whatever the original question is.

What is the purpose of this text box?  I tried clearing it out and typing something else but it doesn't seem to make a difference.  Does it actually do anything?  I don't see it displayed anywhere, even after I type in something else.
