BuddyPress.org

I created a custom filter for my BuddyBar though not having a function to work with,
eg: `$BuddyBar_logo = ‘‘ . get_blog_option( bp_get_root_blog_id(), ‘blogname’ ) . ‘‘;`

I don’t know how to remove the initial echo in $bp_adminbar_logo

`// **** Custom BuddyPress admin bar logo ********
function custom_adminbar_logo() {

echo ‘‘;

}
add_filter ( ‘bp_adminbar_logo’ ,’custom_adminbar_logo’ );`
