Hi Nori,
You may change the link by adding the following line to your child theme:
beans_replace_attribute( 'beans_site_title_link', 'href', 'http://example.com' );
Will will find documentation and a lot of discussions around Beans HTML API which allows you to modify pretty much everything in Beans via your child theme.
Happy coding,
Thanks, that did the trick! I'll look though API documents.
Nori
