Mladen,
There is no tone in email messages... I was not annoyed at all! And you
really do not want to hear me sing, small children weep and dogs howl
:)
I just wanted (at the expense of the oh so massive royalties all
authors get) to make sure that the person you were helping bought the
book he really needed.
I will say again, publicly, something I tell everyone who writes
privately to correct me when I make a misstatement:
"If I have posted something wrong, please tell the list. I don't have
an ego about that -- I want people here to learn the RIGHT things."
I just figure everyone on the list operates under that same principle.
