Header: Link in custom logo

Hi,

at the moment I’m testing this nice theme… But there is one question at the moment: My problem is that I want to configure the custom logo with the map-tag to link to two different sites. If this is not possible, I want to have no link.

When I click on the custom logo in the header it returns me to the main-adress of my wordpress-installation. Is there a possibility to delete this link totally? In which file is this link defined so that I can try to adress to sites with the map-tag?

Thanks for your help,
Tim.
