Go to the Admin "home" (select ADMIN from the dropdown next to your avatar). Select "Challenges" from the left-hand nav bar. Challenges are helpful when you want to bucket a group of questions into a specific topic area (e.g., Just For Fun, HR Metrics, Project XYZ, etc).
To see your newly created challenge, go to the homepage, and select Challenges in the sub-navigation bar. Note that if you like seeing the different challenges, and would prefer this be your default homepage (rather than the All Questions view), simply Contact Us!
