Back in the day when Forum Board script was beginning to be popular like phpBB etc, each board has admin team, moderator and editor team, those moderator and editor want to show off that they have been very helpful in forum by "edit", "approved", "warn" the users and posts, so in DLE if you want to show to the article authors that who has approved their posts in your site, you can do so easily!
Note: this hack can be used in combination of Display the author details in fullstory and it's very small hack which maybe helpful for those websites who want to show the person who responsible for approve the articles within the website
Note 2: you can also display this information to specific usergroup by using standard group/not-group tags so certain user group can see this detail only
Note 3: The hack has been tested with DLE 9.x and 10.x, it might be working with 8.x but not tested
Note 4: To reduce server resources, we would like to use this hack only in fullstory, but you can add it to shortstory and custom page (show.short.php and show.custom.php)
