I'm having a problem with this idea.
1) I want comments. I assume that requires a post and not a page. Is that correct?
2) I want to link to certain (comment only) posts - without having those posts appear in the normal sequence of blog posts.
In other words: Can some posts be prevented from appearing as blog posts? If I set them as pages, that would work - but no comments are allowed on pages (or so I believe).
