At La Trobe University we use Blackboard Collaborate, a Virtual Learning Environment (VLE).
If it is intended that you are to engage with your lecturer and peers in a VLE, the link to access it will usually appear in your LMS subject. Your lecturer may also communicate (via email or the LMS) a URL or web page where you can log in.
For assistance (for example if you have a question about your subject or expectations about your engagement in the VLE) you should contact your lecturer or tutor.
See the Collaborate Knowledge Base for solutions to common issues.
