Dear Marcos, dear David,
I am facing a similar problem: This Monday I had submitted an event, which takes place on Friday. Yet, the event is nowhere to be found, if I click on the link in the email, then I can still see it in preview mode... And even I am not sure if I might have violated some rules? And I also have no idea how much turnaround time it usually takes to release a submitted post. Maybe I am too impatient or maybe I submitted too late and am just expecting too much...? But it would be good to hear from you to be able to avoid similar situations in the future...
