function change_footer_admin () {return ' ';}
add_filter('admin_footer_text', 'change_footer_admin', 9999);
function change_footer_version() {return ' ';}
add_filter( 'update_footer', 'change_footer_version', 9999);
Place the above code in your themes function file. The above code allows you to edit the admin footer version number and text links. Just alter the html in the return of each function. I recommend removing the version number for security reasons. There are a lot of tutorials out there that tell you how to remove the generator tag from your WordPress header to hide the version number put they forget if a user registers they can see the version number in the admin footer page. If you build WordPress installations for your clients this footer area is good for displaying your own support links etc.
