Nursery for New Members

Been away for a short while and just popped back to grab something from my private messages stash only to discover that I've been relegated to the Nursery. Does this mean my PMs are gone? If so, that is an enormous pisser.

That seems to be happening quite a lot lately. I think it happened to Murtle, too. I should think that PMs would be restorable once your Nursery status is rescinded?
