Header Link: Please Help!!

Hi,

First off, I love the theme and forum. Thanks to all who participate!

The site is Lakehome Blog:
I set up the header to link to the site root using the bfa_header file on line 56.

It does link back to the site root. I have no other area now to "return to home" for users wanting to stay on the blog.

I need the header to link to the siteroot on the blog homepage only. Right now it's set up to link to the siteroot at all times.

As you get deeper into the posts I'd like the user to be able to click the header to be able to return to Blog Homeinstead of Site Root.

Please help!

Thanks in advance
