You can use a combination of challenge groups and user groups to create sub-communities of users. For instance you might want to run a separate challenge on a single topic (e.g. "improving customer response times") across a number of departments or divisions ("marketing", "support", etc.) but want each department to only see their challenge. To achieve this:
- Create user groups containing the users for each group (marketing and support)
- Create a challenge for the marketing department (e.g. "Better customer response through EDM"). Configure the challenge to be available only to the marketing users group.
- Create a challenge for the support department (e.g. "Reducing support call times"). Configure the challenge to be available only to the support users group.
- Create a challenge group (e.g. "improving customer response times")
- Add both challenges to the challenge group
Now, users from either the support or marketing groups will see a challenge group called "improving customer response times" under which they will only see their individual challenge.
Administrators will see both challenges under the challenge group.
