It is considered rude to take discussions off the mailing list unless it
has been agreed upon beforehand -- I have added questions at back
in to the CC.  Additionally, top-posting is discouraged on these mailing
lists.  I have corrected the format and responded in-line below.
Additionally, you seemed to have ignored my request to format your emails
better by wrapping your lines. 

In any event, you can't lower the securelevel on a running system -- that
would defeat the purpose.  Modify the setting in /etc/rc.conf and reboot
your system.
