Every player can create a community.
You need to open community icon and choose “Create a community” option.
In the pop-up window you can choose the logo, its color and background.
You need also to name the community. It is strictly forbidden to use foul expletives, insults, and obscene or vulgar words or phrases in the names or descriptions of communities.
Some communities impose entry restrictions, such as minimum player levels or personal invitations required to join. "By invitation" outlines the idea that other players can only join your community if they receive a personal invitation to do so from you or any of the moderators that you appoint.
The member of public community can invite friends to join.
