Understanding public and private teams
When creating a new team, you have the option to make it public or private, but before making that decision you need to be aware of the differences between the types.
A public team scenario: Peter, the office manager
Peter is responsible for managing the company office in Portugal, so he can do this more effectively and communicate with everyone else. Peter has created a new team for the office where he posts everything relating to it. Anyone working in Portugal or visiting the office can join the team to access things such as the office location and working hours, or simply to ask Peter or any of the other office members for something.
