We are working right now on implementing a Discord <-> MC server chat link. The Sky Adventures and the Continuum server have the plugin already installed which provides a bi-directional chat which enables us to help the players also when no staff member is on the server.
Tests for the new server are on the way. Right now i have two test setups running to see stability and compatibility with plugins. One is running the Enigmatica 2 and the other the FTB Stoneblock 2 modpack. After all tests are over the one with the best performance will go public.
We have now a Terrafirmacraft community sever. Its a whitelisted server. I order to gain access to it you have to be invited by one of the staff members and you have to be a know player on the network.
