% Wikipedia is a free encyclopedia written collaboratively by volunteers around

% edit in order to communicate and discuss updates to various articles on        
% Wikipedia. Using the latest complete dump of Wikipedia page edit history (from 
% January 3 2008) we extracted all user talk page changes and created a network. 
%                                                                                
% The network contains all the users and discussion from the inception of        
% Wikipedia till January 2008. Nodes in the network represent Wikipedia users and
