Ghastly, let me explain what they mean, and the only reason I know of it is because I got comments like this on other forums (You think this day and age this wouuldn't be an issue)

If person a has say 30 posts displayed, while person B has 10 posts displayed, and they are on a thread 30 posts long. Person B will link something from "page 2" (even your first post has a "page 3" extension shown) But for person A who has 30 posts displayed, will not see the link person B gave because a page 2 does not exist for them. What they are saying if you click the post number in the upper right hand of the post, you get the direct post link and everyone will be able see it, regardless of settings.

How come people can't explain this in detail? It is clear Ghastly has no clue what people are talking about.
