Communities are ways for the players to team up; they are designed to help one another, take part in fairs and other events together, and chat.
Every community includes no more than 50 members.
The player can join only 1 community at the same time.
During 3 hours you can join and leave no more than 3 communities; then you need to wait 3 hours till this option is available again.
The members of your community have the special “community” icon on their avatars in the neighbors` bar.
