    Thanks, Alex. I'm glad someone is watching.
    I'm a little confused. What did I do wrong?
    I would hate to offend the wonderful members of this community so I guess I
    need some input on what offended you.
    On all the bulletin boards I've used, where the message is sent out by
    email, the subject matter preceeding the response is included so that the
    response makes some sense.
    An isolated sentence with no clue as to what it refers other than the
    Subject title can be very meaningless and out of context becomes a waste of
    time.
    I wouldn't want to waste your precious time.
    Heaven forbid I should break some rules but if the rules make the bulletin
    board useless then the rules need to be changed.
    So despite your ire, I will continue to include sufficient of the preceeding
    information, even if summarized, so each contribution can stand on its own.
    The content following this response was left intact in this case because it
    is essential for other readers to review the subject matter and understand
    where I comitted this cardinal sin.
    And who appointed you the bulletin board policeman?
    And are you going to have me kicked out. OOooo I'm so scared.
    I spend way too much time on this board anyhow, you would be doing me a
    favour.
    Next time you want to be critical, make it constructive criticism. Just
    ringing the alarm bell without explaining in particular what should have
    been done only wastes your time and mine.
    Nah ninny na na I own a SAIL BOAT not a Trawler. Fooled you all. And with
    my twin 6V72s and 71 feet I can out perform any of you stink potters when
    I'm stink potting too. :o)
    SO shove it up your exhaust pipe, I don't need this BB anyhow. Just because
    I'm a girl it doesn't mean I don't know what I'm talking about.

    Bye.
    Andina Foster,
