Making tables transparent has been responsible for .. what, two-three support requests a day, if not more? Whatever the number, it definitely counts as a frequently asked question.
My suggested addition (Just sticking it in at the bottom):
-TRANSPARENT entries: Many people want their entries to be transparent so that their text is directly over their background. This can be accomplished in most browsers by adding a new line to your GLOBAL_HEAD, like this:
GLOBAL_HEAD<=
<STYLE TYPE="text/css">
<!--
body { background-image:url(http://www.urlbackground.jpg);
;){kind=link}
background-attachment:fixed }
table, td, .shadowed { background:transparent }
-->
</STYLE>
<=GLOBAL_HEAD
