Currently you can join our community by actively participating on the server. Our primary form of instant communication is on our Discord server. We have a Youtube channel where we post updates, features, tutorials, and more so subscribe to that so you don't miss out. We also have a Googe+ account and a Facebook page, but these aren't very active right now.
We are planning to do additional things to promote a community among our users, including forums, a messenging system, and a wiki. However we have not finished these projects yet, so please be patient while we work on them.
