Sylvain Le Gall has videos from OCaml Users Meetings through 2011. He has posted some from 2008 and 2010 on YouTube. Just adding these links to the videos page would be boring. Let's consider how to integrate them better. Currently oud.ocaml.org points to external pages for the 2011 and 2010 meetings, but maybe we should create an archive of past meetings properly integrated into ocaml.org.
What have you got in mind ? Archive them by year ?
Do you want to link/embed them or host them ?
