We have a unofficial discord going, besides this forum, it's a good place to discuss what's after MBT.
If you don't know what discord is, well... It's fundamentally a VoIP program, but in our case, think of it as a chat with channels for each category..
And, if you wanna talk with somebody, you can simple go in to a voice channel and have a talk.
In any case, please feel free to ask for a link, discord work in the browser, but it is best if you download the program.
Unfortunately, I can't provide a link for you here as I'm not a admin there myself..
