More Formatting Questions

I apologize if it's been awhile. I haven't been well/upright much the last two weeks, for reasons unexplained and I wouldn't explain a publishing blog anyway.

Hi.

* When starting new chapters, do we just make a few returns (so there's obvious white space) or start each new chapter on an entirely new page?

A new chapter should have a new page.

* Also, when changing POV in a scene, I always used to see * * * * * to indicate the switch. Now I sometimes just see white space. Does it matter how you indicate the POV/scene change?

As long as they're space it doesn't really matter, but you can add something like ****s or ##s if you want, as long as it's unobtrusive and doesn't confuse us into thinking we're reading a new chapter.

* I've looked at several agents' blogs, and different agents suggest different footers/headers. Is there a standard? i.e., should it be book title/name or name/book title at the top left? Also, should the page number appear top right or at the bottom?

Standard is:
AUTHOR'S LAST NAME - PAGE NUMBER - TITLE
In the upper right hand corner of the page on every page. Minor alterations to this, such as the author's full name, or reversing the positioning of the title and the last name, or putting it on the bottom of the page, are not a huge problem unless the agent specifically told you what to do on their website and you didn't do it. Then you look lazy/obnoxious.
