MediaWiki:Achievements-create-edit-plus-category-content

You can create new badges for a specific area on the wiki. It's helpful for improving areas that need improved, motivating users to edit, or just making it more enjoyable to edit a certain area. To create a new track, just type in the name of the category in the box below, and click "Create track", the track will be created. It will take you down to the new badges, where you can customize the name and photo. Once you're done, just press save.

Once you have done the customization, click the "enabled" checkbox to turn on the new track, and then click "Save changes". Users will see the new track appear on their user profiles, and they will start earning badges when they edit pages in that category. You can also disable the track later, if you decide you do not want to highlight that category anymore. Just clear the check box next to "enable". Users who have earned badges in that track will always keep their badges, even if the track is disabled.
