General feedback can also be sent to feedback(at)fosdem(dot)org

@fosdem I've starting mass writing feedbacks, and 1 in 3 talks leads to the "Resource Not Found" error — from the mismatch of slugs in the pretalx database and the website.

Is the feedback stored when this error appears?

I have been told that the feedback should be stored that it's just a redirect that's failing because of changes in schedule urls for these talks...
