A little bit along similar lines, I find it useful to have the  
following in my preamble:

%begin---------------------------MARGIN NOTES (Ask Nelly Practex 2005  
Vol1.)---------------
\newcommand{\query}[1]%
	{%begin definition
		\marginpar{%
			\vskip-\baselineskip %raise the marginpar a bit
			\raggedright
			\footnotesize
			\color{red}
			\itshape
			\hrule\smallskip#1\par\smallskip\hrule%
				}%
	}%end definition
	
\newcommand{\removequeries}%
	{%begin definition
		\renewcommand{\query}[1]{}%
	}%end definition
%------------------------------------------MARGIN  
NOTES------------------------------------------end
