As long as we have forums here on our site, there is no reason to have a Discord. That's a decision I made when upgrading the forums to Xenforo. If people are chatting in a Discord, then there's no need to have these forums, and would only result in a defunct part of the site. We also barely have enough volunteers as it is to keep on top of the various social media activity and content creation, so another platform to manage and maintain is just out of the question.
We currently do not have a Discord, and don't have any plans to create one in the future at the moment. That's my call though so I carry that decision on my shoulders alone. If I step down and someone else takes over, then perhaps they might disagree and bring in a Dojo Discord. Nothings impossible so wait and see I guess.
