Hi @Gien,
no problem. I created a topic describing how you can enable email notifications when you are pinged. I think as BoST member it would be good to activate it.
Regarding you comment above. I think it is great but off topic here. This thread is to discuss the list of challenges.
A better place would have been in a new topic in the “places & spaces” channels category or as a quick comment in the BoST & Association Chat.
