At least we still have a forum. Bethesda seems to think Discord is one now, they shut down all of their forums. Try having an opinion or suggestion in that mess.
Yeah, Freddo (occasional co-mod here too) just told me about that. :| I'm quite sad really. I arrived there in the TESF "Oblivion Tan" era and felt quite at home there; of course "not as good as it used to be" had already gone through several iterations by that time and I did the same once it became BGSF and switched to the post-apocalyptic black-and-grey theme, but it still pootled along until the pretty disastrous switch to the monochrome smartphone-styled "games discussion only" format. I think the end was inevitable really.
Although forums in general are seeing much less traffic than they used to, there's no plans to "outsource" Larian Forums to social media or Discord and they're still the same as they always were except for periodic software updates. IMHO the early Divinity-era theme could do with an update (and I've toyed with the idea myself but I'm no sort of graphic designer) and doing so would probably annoy more people than anything.
As for communication, I have my own thoughts about that but I'm not sure another opinion would be helpful. I don't know any more than anyone else though, fwiw.
