I'm really sorry guys. But I have to do this. NodeMC isn't really being maintained any more.
The reasons are twofold. For one, I've lost much of my interest in persuing v6. It was fun, but I struggled to learn ES6, which Jared rewrote all of NodeMC in for v6. Absolutely nothing against him, he's a great guy doing good work but unfortunately that rewrite sort of killed my interest.
Also, Jared, Matthew and I have all been busy with either school or other projects. Unfortunately, this means that we haven't had time to devote to NodeMC. I suppose that's just how it goes for projects like this sometimes.
So - if you want to take over NodeMC, please do. It was a great project that I loved seeing progress. It's unfortunate that we've not been able to maintain it or get v6 out the door.
All you have to do is either tweet me or open a new pull request with whatever you wanted to add. I'll still answer issues and moderate pull request, but I personally will not be contributing much if any code.
If you're looking for v5 (stable), it's at the v5-dep branch. This is so I can still keep that code but also make sure you can see this message.
Really sorry once again, but I hope you guys understand.
Cheers,
Gabriel Simmer
