The document summarizes the University of Edinburgh's experience piloting and adopting the virtual classroom tool Collaborate Ultra. It describes four key use cases of the tool: for online postgraduate information sessions, an undergraduate student induction pilot, biosafety training courses, and a university-wide lecture recording rollout. Overall, users found Collaborate Ultra easier to use than the previous version and liked the improved audio and video quality. However, some issues were encountered around participant limits and the lack of certain collaboration features. The document concludes that renewing Collaborate for another year would allow further improvements and adoption across more use cases at the university.
