Can anyone help me to exclude main blog post from Recent Networkwide Posts widget?
In my case all posts on main blog are published by one user. But changing ‘user_id’ => 0 to ‘user_id’ != 1 did not help.(My php skills are very limited)

( bp_has_activities( array( ‘action’ => ‘new_blog_post’, ‘max’ => $instance, ‘per_page’ => $instance, ‘user_id’ => 0, ‘scope’ => false, ‘object’ => false, ‘primary_id’ => false ) ) )
