This is a bit off-topic, I apologize in advance.
Someone sent byuu (author of bsnes/higan) a shipment of 100 PAL games from Germany to the USA so he could scan and help preserve them. However it's been 45 since they were sent and it still hasn't arrived.
He tried to contact USPS but he is being ignored. If someone could somehow draw attention to this, maybe by creating a new topic here (byuu has tried, but he is a junior so he has no privilege to do it), or by posting this on some news site, that would be great.
If this package turns out to be lost byuu will probably cease his preservation efforts and is going to pay back for those carts as he feels responsible (he is the one who asked for them).
If you are interested you can read more on his forum:
