I've come over from vB and had it set up to exclude 2 forum/nodes on the what's new section as they were busy RSS feeds that users (rightly) didn't want their "New Posts" list full of. They have the choice to go read the section manually. Which worked for my community.
On the old forum I had to manually edit something and added exclude comment with the number of the forums/sections/nodes I wanted to exclude.
Can this be done with xF or something similar? Please say it is!
