Your host is a little new to VRChat still, please understand
Kanpai to the first VRC Mahjong Night starting in roughly an hour (2AM UTC) in the Tanki world
World: https://vrchat.com/home/launch?worldId=wrld_06256a1e-cc14-4946-8258-da94909c7daf

PLEASE CONSIDER replying to this post if you are interested in playing as Tanki only allows 4(four) people to play at a time, this way we can figure out instances in advance if they are needed. If you are interested but this time doesn't work for you, consider replying a time you can to play.

Otherwise, feel free to jump into the public instance(s) to watch/hang out/have a drink.
You don't need any experience at all, you don't even need to wait for your headset to arrive, or worry if you prefer to be mute, all is accounted for. Just have fun with some mahjong.

I'll probably jump in a little early to scope it out, and will gladly stay for a few rounds or more.
