Adjustment of Official Operations and Communication Channels
In order to better strengthen community communication, promote the efficient development of the community, and establish an open and democratic mechanism in which all community members can participate, official operations and communication channels have been officially transferred to Telegram/Currency. Communities maintain daily communication, contribute to discussions, receive feedback and assist in solving related problems.
In the future, Battle Camp leaders will act as representatives and participate in the high-level monthly meetings of the Alliance to enhance communication. More community leaders are welcome to set up their own Battle Camps to jointly develop the six-domain community!
