Howdy! I see the old noclip post about a skype group but I imagine that more of us are using discord these days, yeah? I just set a channel up for Wingame speedruns:

That's a perma invite link so it should be fine. If you're not already on discord, it's a great piece of software and you should check it out! One of the things I'd like to get done for this in the near future would be a Now Live bot, like the VVVVVV discord channel has.
