You may see user activity at a more granular level, as well as when members joined or left your DataCamp for Business group, if you click on the "by course" page.
i. The column "JoinedGroup" is reflected in the "by course" tab. This is the date that new members of your business group joined.
ii. The "groups" page, on the other hand, shows when users "created" their DataCamp accounts in the column "CreatedAt," rather than when they joined your group as a member.
