To enable Group History for all groups of a certain group type, begin by locating the group type in:Admin Tools > Settings > General > Group Types.In the General section of the Group Type Details screen, check the Enable Group History checkbox. You can customize the group type's display options in the Display Options section by assigning it a color and icon. These options come into play in a number of the Group History views, but we'll get into that later. For now, click Save and Rock will enable the history and options for that group.
