WordPress MU

I'm attempting to create a theme for WordPress MU that, for simplicity's sake needs to contain some links to the main home page for the site.

I wish to do this in a dynamic manner so, for instance, I could pull the logo from the main Blog, and not need to duplicate it within the theme.

What I've got so far is:

"><?php bp_site_name() ?>

Which would display as:

Site Name

on the main blog, but displays as:

Site Name

on example.domain.com.

Is there a way (other than hard coding the main blog's URL into the theme itself) where I could alter that original code and display the main blogs url (http://domain.com) on the subdomains?

You might try using the function

<?php switch_to_blog(1); ?>

before calling the

<?php bp_site_name(); ?>

which should give you the correct link.

Don't forget to call

<?php restore_current_blog(); ?>

after displaying the link so the rest of the pages uses the correct blog.
