If I go to User Settings the node User Posts is linked as "Your Blog Stream" and later there is a checkbox "Show blog on homenode:" but my writeups aren't a blog

in other forum software, the "blog" section is not just another name for all the users writeups, its a separate section

now given there is some choice of sections ... if its just root nodes I post that might make sense,

but there is no docs on this,

So I'm trying it out
