Thread:Project:Support desk/Special groups edit pages belong to them&change default mail content

MediaWiki 	1.22.4 PHP 	5.4.26 (apache2handler) MySQL 	5.5.36

Hi~Now my wiki lets all users except "sysop" unable to edit pages. However, now the requirement changed: let special group like:group A ,can edit the page belong to that group. What should I do now?

And the other question is that is it possible to change the content of mail which is sent to users who monitor some pages? And which file should I edit?

Any help will help me!! Thanks~
