Alright guys and girls. There is now an official Rockstar Games Discord with a GTA6 channel.

Got this with the GTAO weekly updates. Yes, it's official.

"We’re excited to announce Rockstar Games is now on Discord!

We’re inviting you and your followers/communities to be amongst the first to join the just-launched official server. Connect with the community to team up with like-minded players, organize sessions through LFG channels, catch the latest updates and announcements, and more."
