As far as I understand it, the NMA Underground Discord is aimed at different things compared to the NMA Discord server. The NMA Server is for general NMA, it's public and anyone can join, it's also a generalized server with many channels and topics, etc. The NMA Underground Server is for socializing and is aimed at group activities like playing games or watching movies together and only NMA Site members can join. They both have different focuses and purposes. I haven't joined the NMA Underground because I haven't had time to even be on Discord for almost a week or so now, and I doubt I will have much time this month either since I am super busy and my sleep has been getting worse again. But it does sound interesting.
