This video tutorial demonstrates the steps to download and install the Blackboard Collaborate launcher. 
It then shows how to join a Collaborate room from a guest link created by an instructor.  Once a student joins the session, they can:

• Use Chat to send text messages to other participants and the moderator during the session
• Run the audio set up wizard 
• Get additional help from the Blackboard Collaborate support page, as well as Wilmington University's Technical Support phone number
