You can create a new set of badges, called a Badge Track, that gives badges to users for editing pages in a particular category, to highlight a particular area of the site that users would enjoy working on. You can set up more than one category track, so try choosing two categories that would help users show off their specialty! Ignite a rivalry between the users who edit Hero pages and the users who edit Villains pages, or Omnitrixes and Episodes, and so on.

To create a new Badge Track, type the name of the category in the field below. The regular Edit track, and others, will still exist; this will create a separate track that you can customize separately.

When the track is created, the new badges will appear in the list on the left, under the regular Edit track. Customize the names and images for the new track, so that users can see the difference!

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. Users who have earned badges in that track will always keep their badges, even if the track is disabled.

Note that even after the highest listed badge is earned, copies of that will continue to be earned, just for different numbers of edits.

This can help to bring another level of fun to the achievements. Try it out!
