A new platform has been launche that brings together event organisers and academic speakers http://www.speakezee.org/
Researchers can create a profile and add a video of a public talk if they wish. After only 3 weeks live there are more than 400 academics from across the UK.
Speakezee has been started by University of Bristol academic, Professor Bruce Hood, but is not an official University project. It is a UK service open to everyone from every University. Bruce hopes to achieve country-wide coverage.
