Is there a way to get this to show the members for only one blog?

I have a Multisite install, but I want to allow Member Registration for only one blog (that is, everyone will be an author on this one blog, not creating their own individual sites).

Is there a way to get the Members Directory to ONLY show members of that one blog, and then have the page that is created be linkable from within that blog (right now, I have to go to the main network site to see the Page, so I can’t link to it from the blog that will have the members)?
