It is a collection of tools that you can use to help generate excitement and quickly and easily spread the word about Release 9.1 to the many stakeholders at your institution."
"Listed below is an overview of the primary new features that faculty and TAs will find in Blackboard version 9.1. Blackboard is tentatively scheduled to be upgraded version 8.0 to 9.1 in May 2011. "
