Just create a board for new members. You know it will have to be done sometime, so the sooner the better.
It's like Brexit. It was obvious from the very beginning that it would have to be a clean break with WTO rules, but the unicorns are trying to push as much money out of the country while they can.
Give us a couple of new member boards, and restrict newbies posting elsewhere. Lets rebuild Bitcoin Talk to take advantage of all the changes that are happening in the financial world. No thread starting until you have a post count of 5 would help as well.
Some of us 'newbies' have actually joined Bitcointalk to learn more. If we are restricted to 'newbie' boards, and we have questions to pose, how would we get the answers? It would be pointless having newbies answering newbies questions, and the more experienced users wouldn't be bothered by the 'newbies' boards.
