Isn't there a Discord invite available on the front page? The staff is available to moderate, and multiple projects have their own channels. Not super sure about RemedyBG, but I'm assuming the author hangs out there.
As far as the forums thing, there's tremendous value in a forums board that closed real-time systems can't offer. Long-form asynchronous discussions -- where you chew on a topic and reply at your own pace -- isn't encouraged in a chatroom. Then there's the side-effect of future users searching the forums, whether or not they're a part of the community. It's been like a Handmade Stack Overflow for many people.
The real solution, according to Ben Visness
and the rest of the team is to bridge Discord and the forums (see the new community showcase on the front page.)
Eventually, multiple sources (Twitter, IRC, etc.) might also be bridged? Sounds awesome.
