The Challenge extension allows challenging other users through Special:ChallengeUser. When challenging another user, the challenger gets to lay out the terms, i.e. what users must do if they win/lose (for example, edit a certain page or write a new page, and so on).

Challenge history and statistics can be viewed on their own, separate special pages (Special:ChallengeHistory and Special:ChallengeStandings, respectively).

Like many other social tools, Challenge was originally developed at ArmchairGM, where it was used for a while between 2006-2007. It was fixed in late 2014 by Jack Phoenix for ShoutWiki.



  • Download and place the file(s) in a directory called Challenge in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'Challenge' );
  • Run the update script which will automatically create the necessary database tables that this extension needs.
  • YesY Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

User rights[edit]

The Challenge extension adds one new user right, challengeadmin, which allows picking the winner of an individual challenge when viewing the details of a challenge on Special:ChallengeView. This user right is granted to the sysop (administrator) user group by default.


5. UserActivity changes — this is from Sports (Gaming Newest).php (with some tweaks for fowards-compatibility & best practises, obviously):

						case 'challenge_sent':
							// @todo FIXME: i18n
							$challenge_link = "<a href=\"index.php?title=Special:ChallengeView&id={$item["id"]}\">challenge</a>";
							// "issued an accepted [[Special:ChallengeView/$1|challenge]] to $2 $3",
							$output .= "issued an accepted {$challenge_link} to {$user_link_2} {$item_time}</span>";
							$output .= "<div class=\"user-feed-item-comment\">{$item['pagetitle']}</div>";
						case 'challenge_rec':
							$challenge_link = "<a href=\"index.php?title=Special:ChallengeView&id={$item["id"]}\">challenge</a>";
							// "accepted a [[Special:ChallengeView/$1|challenge]] from $2 $3",
							$output .= "accepted a {$challenge_link} from {$user_link_2} {$item_time}</span>";
							$output .= "<div class=\"user-feed-item-comment\">{$item['pagetitle']}</div>";

5. For UserActivity::getTypeIcon():

	case 'challenge_rec':
	case 'challenge_sent':
		return 'challengeIcon.png';

6. Test email i18n messages out, improve the English text(s) as necessary and finally translate them to Finnish (fi)
7. Fix the "counter terms" (internal status code, as used in ChallengeView::displayChallenge etc. for this case is 2) functionality; right now it sends the challenge into a de facto infinite loop as far as the challenger and challengee are considered; I'm not sure if a challenge admin can do stuff with it.
