<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I apologize for sending out a post three times because
of</FONT></DIV>
<DIV><FONT size=2>a configuration problem in my mail client. I tried
twice</FONT></DIV>
<DIV><FONT size=2>so that there were already two unsent mails in my
outbox.</FONT></DIV>
<DIV><FONT size=2>After I fixed the setting problem, I forgot to delete
the</FONT></DIV>
<DIV><FONT size=2>two and tried again, so you may have received my
three</FONT></DIV>
<DIV><FONT size=2>equivalent posts.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I'm sorry for the inconvenience and apologize
again.</FONT></DIV>
