Remove WPMU links from footer?

I have installed the business themem and am slowly gettign the hang of setting it up.

Is there a specific business theme manual?

I'd also like to know if we are allowed ot remove the WPMU link from the footer. If so, can youplease tell me how to do it.

I've edited the copyright info in the footer.php template but not sure what to remove to stop the theme links appearing.

Thanks.
