Hello everyone, I am actually running a wiki page and i have a question I dont know exactly how to do in order to protect some pages from editing from some users. I explain an example to illustrate my question Imagine i have a wiki with information of Madrid and Bacerlona. I have two different group of user Mad and BCN I create (i guess as follow) $wgGroupPermissions['Mad'] = $wgGroupPermissions['user']; $wgGroupPermissions['BCN'] = $wgGroupPermissions['user'];

How can i do to protect articles of Madrid from bein editing by BCN people? something like that $wgGroupPermissions['BCN']['edit']['mad articles'] = false;

Thank you very much in advanced!
