We are sorry it is taking such a long time, and sorry there were no updates. So the current state of the forum is that it’s mostly finished. The biggest things that aren’t done yet are mobile support and legal stuff.
We don’t have an ETA and realistically things will continue to be pretty slow in the development. The ones that are working on the forum work on it in their spare time when we feel like it, and vanilla forums isn’t that fun to work with. But recently we had a chat with the Brackeys Team about the forum and what needs to be done, so things *might* speed up a bit.
Also, I will bring up the open sourcing of the forum (well, the vanilla forums themes) with others, will post back here with new info of course.
