After clicking “Join” to join the challenge, you will be asked to join a team within the challenge.
Teams are fluid and are not necessarily limited by the department you work in. You may join a team where your closest colleagues work, or create a new team for you and your friends.
If you decide to create a new team, you will be able to invite people inside the challenge.
Please note that you cannot change teams without leaving the challenge and losing all your progress. So choose them carefully!
