It is so sorry to disturb you .But why I just receive the e-mail of
questions about Bro ,and can not receive the answer of the question .For
me ,the answer have the importance as well as the questions .It my pleasure
to receive your help .
Thinks a lot .

It's because nobody in the bro mailing list answered. My guess is that it's just you and I are the only ones subscribed to the bro mailing list...

It could be that the folks who actually answer the questions, like Vern,
are so busy they just haven't had time to respond.
