jvinch, ok. I’m not sure what else to tell you about this except create a new file, name it anything you want .php, drop it in /mu-plugins. The plugin should contain the function bp_blogs_record_post() as it is in bp-blogs.php.

1) rename the function something else: jvinch_bp_blogs_record_post()

2) add the filter code that skips recording blog posts for blog id 2

3) unhook the current bp_blogs_record_post() and hook up your modified function instead

4) test it out

#2 above would be somthing like:

if ($blog == 2) return;

#3 would be:

remove_action( 'publish_post', 'bp_blogs_record_post' );

add_action( 'publish_post', 'jvinch_bp_blogs_record_post' );

You are doing all this on a dev server for testing of course.
