Dear experts,

I received a letter from other party which I want to use it as a sample
letter. However, in the sample letter, I see a gray (or dimmed) line under
the authorized signature (the end part of the letter). As the line is no use
to the letter, I tried to click the line and delete it but the line could not
be clicked. I then tried to copy the letter contents without the line to a
new document, the line was still there. As I've no clue what the line is
about, what can I do to delete it. Please advise.

Thanks a million.
