As you've told me before IE always does exactly what you ask of it! :-)
I strongly suspect that it's caused by your very weird code at:
<center>
<font color="000080" style="FONT-SIZE: 16pt" face="Arial">
You can READ or POST without signing in or registering
<BR>
<B>
<BR></B>
<font color="ff0000" style="FONT-SIZE: 12pt" face="Comic Sans MS"><center><B>
Hot Links<B>
which contains two opening "center" tags, when there's only one closing tag on the page.
Firefox and Chrome both appear to make a better stab at your intended layout, in spite of the bad code. Your site is not centred in those browsers.
