Thank you Denise for the feedback.

We are working on making the bboard match the brand but let employees know they are on a different site. 

There is a difference in the headers of each site:

public: green (links:I'm a local, etc)

bboard: blue with a BBOARD tag next to the logo  - also the links are Employee, etc.

we plan to add new banners images on bboard to make it stand out more. We will think up other variations / visual queues to let users know where they are.
