Obviously this only lists talks that are listed through talks.cam. Furthermore, this facility only works if the speaker's e-mail was specified in a talk. Most talks have not done this.

Talks organised by Ivan Smith

This list is based on what was entered into the 'organiser' field in a talk. It may not mean that Ivan Smith actually organised the talk, they may have been responsible only for entering the talk into the talks.cam system.
