So to answer directly, I think you need admin powers to "rename" a page, and it should be done with a redirect. An admin (preferably) should run AWB to change all redirects to the new page.
For right now, ABSOLUTELY just update the current page. I can move it :)
You know someone else revealed that his name was Erving before that issue. I didn't believe them. I wonder if it was revealed in the end section of the comic. I guess now it's officially confirmed and I look like a fool :)
