I am keen on using the Rebranding WPMU plugin and after describing the installation process the document reads, -
"Once you’ve done that you need to manually edit the following image files (naturally we can’t make your logo for you):
and maybe wp-includes/wordpress-admin-bar/themes/grey/grey.css"
I did not understand what I need to manually edit these images/files for. Can someone please explain? ( It seems that the login image is replaced once I upload an appropriate image. Can other wordpress logos be replaced by this plugin too? I may be repeating myself here, but what is the editing required for?)
