Unfurtonately you get too drlfom geeback to Webinars and Webcasts. That's why I cleared old contributions from my channel.
I cleared also recording obviously warched by other people.
In detaill the (very old but still up-to-date) webinar with Anne Rozinat and Denis Gágne about Process Mining and Process Modeling. You can find it again on YouTube: Webinar with Anne Rozinat and Denis Gágne.
But you can comment on contributions too without having me deleting them.
