blogs-mu theme, how do I edit the logo url to an external link

Hi,
By default the logo links to my blog home page.
However I would like users to be sent to my website home page and not the blog home page.
How do I accomplish this.
I am not quite good with php.

Theme: Buddypress Blogs-MU
url: http://mytheatrecafe.com/community/

Thanks,
V.
