Clan Message Boards are Coming!

Hypnotik: It is possible, but not a priority. The messages you leave for your clan through this system are not visible to those outside of your clan. When using the API, typically the server that pulls data is grabbing publicly visible information from the API. Since the general public cannot see the messages left on this system (only clanmates/leaders can), adding this to the DPP API wouldn't have much benefit. It's a similar situation to the clan treasury history not being available through the API.  

Hypnotik: There's always direct messaging.  

Hypnotik: There are 2 permission levels currently - Clan Members (all people in the clan can read this) and Officers (only Combat Officer, Personnel Officer, Executive Officer and Commander). Non clan members do not see your messages at all.
