The forums are run on third party software UBB Threads, and I think might even be hosted by that third party (though I might have got the wrong end of the stick there). It’s been the platform for ages now and is clearly creaking and performance levels are unacceptable, and what is needed is a complete upgrade probably to a new package that is run on infrastructure able to cope with the modern world. But that’s not a small job, especially if there’s a desire to migrate all the historic or in-progress discussions to the new platform.
I don’t know how likely it is to happen soon, but I’m hoping that once BG3 is out, Larian might have a bit more attention to spare for us suffering forumites!
