We've been pulling individual users for quite some time, but there was always something missing that tied them all together... Steam Community Groups.
Now, you can add Steam Community Groups to a setting in your AdminCP, and display information about the group on any page within your community!
The users displayed within the group widget are users on YOUR community that are a part of the group. You can configure how many users you'd like to display along with how many lines of description text to show by default, with a 'Read More' link to show the full description.
