\section*{abc}
This is the first column.  Here we do
have few challenges in formatting this 
page.  First is what if we want to put 
a picture across both of the columns.  

\newpage 
This is the second page I suppose.  
This suppose to be a coninuation from the 
first column.  

\onecolumn
This column I hope is a continuation from 
the second column.  
\hfill
This could be another column.  Or something like that.
