Another issue while trying to hide the BuddyPress admin bar on sub-directories for logged in users

Project site: http://nubiint.com
BuddyPress Sub-directory: http://nubiint.com/community

I've enabled the option to "Hide admin bar for logged out users" and it works fine. I'm now trying to prevent the bar from appearing on other sub-directories for logged in users. So I have the following sub-directories:
/business
/int-info
/networking
/tech

I've uploaded the "bp-hide-sub-blog-adminbar" plugin and activated it but it doesn't do anything by default so I add a blog ID as follows:

<?php
if($blog_id != 2) < - /business Blog ID

This doesn't do anything. Am I missing something?

Another issue I notice on the Main MU site for logged in users is the following that appears below the website:

You can see it by navigating to the site above. How do I remove this?

Any responses appreciated.
