ListUsers

ListUsers lists users of various groups in the wiki. Similar to ListAdmins, the list is generated via API, and thus does not require any modifications. However, the group can be manually adjusted. Any change in user rights would be automatically amended to the list.

Installation
Add the following to your wiki's MediaWiki:Common.js for site-wide use:

Usage
Any tag, with the class name, and group name as the id would generate a list of users in that group. For instance: If the id, that is, the user group is not defined, a message will appear instead of the list: "No user group found". If no users are found in a group (technically, that is not possible as An unknown anonymous user is always present for no users, which is apparently, a bug), another message will be displayed: "No users found in the group".

User groups
A full list of supported user groups, that can be used as valid ids, are (case-sensitive): Other groups listed in Special:ListUsers have been purposely struck down, but can be added manually if required.
 * bot
 * sysop
 * bureaucrat
 * staff
 * vstf
 * helper
 * rollback
 * chatmoderator

Adding custom user groups
The script supports custom user groups as well. For adding custom user groups, store them in the  array. For instance:
