Re: Same look for all blogs
… and use the More Blog Defaults plugin to set this theme as the default for new blogs.
“Delete the default theme from your themes directory and then rename the folder with your theme to ‘default’. “
You also have to rename the theme at the top of the stylesheet, and you *should* delete the home.php in the copy of the theme just for blogs.
I know a bunch of us have done this already – someone needs to go dump them in the repo.
