While I'm on this mod's Discord server, isn't this forum a perfectly valid place to talk about this mod, including questions about it? I mean, what else would this thread be for, if not discussion and info on this mod? While Discord is a very popular program, you're asking people on this forum to use third party software that isn't directly tied into Terraria like tModLoader. So they could have an account here, use it, and then find out they have to get another program just to ask an question they probably thought they could do here. I would argue it would be easier to find answers in this thread (while it remains small), as it has way less messages than the Discord server will.
It seems questions about the races are somewhat common in this thread already. Maybe a FAQ in the first post could help, so even people who find this thread via the mod browser would be able to see it?
