Subtle but necessary changes to the Blogs MU theme

Change #1: Remove the One community multi-blogging solutions... text. Ii thought this was done by modifying the options-functions.php file but the changes don't seem to have taken.

Change #2: Add a Register / Login form in place of the network intro post text on the home page. Basically you'll see the same form you see on the Register page or something customized. I've tried hacking this and adding WP-Cycle but can't seem to find the right location. If anyone know if a Contact 7 form can be added I'd be really grateful.

Any responses appreciated.
