I'm not getting rep. image notifications anymore. And I don't think all my Image Submission Declined messages are arriving either.
I submitted four images yesterday evening for Age of Steam Netherlands. I got notified (and geekgold) as they were approved.
Somebody nominated one of the images to be a representative image, and it was approved. I didn't get a notification or any geekgold for it.
So, it does look like we have some buggies.
