Users in FlexiServer system are divided into several teams.
Each user's team property is set during user adding. It can modified later, but only by admin user.
Users added during initial step wizard are set to be in "DefaultTeam", which can be modified afterwards.

Total team list is shown in "Edit team list" on the main page of FlexiServer, which can be used to add or delete a team in the system.
DefaultTeam is required by FlexiServer system and it is not allowed to be deleted.

The users in the same team can see each other's status and use popup message to communication with each other.
