I've been fiddling with permissions and I think I'm missing something that's probably basic and obvious. I have about 10 forum sections for my 600 members. So far so good. I want to create a new forum node where all 600 members still have access to view and post in, but I also want to create a new user group of, say, 10 new members that can only view and post in the new forum node, and all other forum sections are invisible to them. Can someone please point me to the instructions or provide some guidance? Thanks in advance!
