BuddyPress.org

not sure how to use (bp_adminbar_blogs_menu() function in /bp-core/bp-core-adminbar.php) it. I tried this:
a href=”‘ . $site_url . ‘wp-admin/post-new.php”‘ . __( ‘New Post’, ‘buddypress’ ) . ‘/a
but it showed this in my address bar:
http://mysite.com/%27%20.%20$site_url%20.%20%27wp-admin/post-new.php

It didn’t show the user address. What part am I missing? Thanks
