How about leaving the old forum open for public use? McNeel doesn’t have to frequent it nor answer questions, but if it were left open, we who like the older format could continue to use it. Also why not use the older forum as a place to post 3dm files and vb and python scripts?
I get such quick and useful help in the old forum recently Pascal and William posted a paint by numbers script I needed and the updates to tweak it were fast almost instant. So for us users the older forum would still be still be a great place and format to continue to post and share files and even get quick help just amongst us users.
