I'd like to change the title of my blog (link usually at top left corner of site) from <h1> to <h2>. (for example, for this website it's the stackoverflow link at the top left corner)
I need to know where the .php file which renders the title is located.
Right now, I can see that the title is being rendered within a do_atomic, but i'm not sure what that means or how to go deeper into it.
Thank you.
