If the owner had blocked finds, you would not see the "show finds" button. So I'm going with Option 1.

Or possibly Option 4, "This box has been found but the finder did not record it."

But I"m rooting for Option 1 because yes, that WOULD be so cool!

That's what I would say too, option 1. You could be the FF. And if it happens to be opt 4 you can by the first to log it on AQ. Either way it sounds like a awesome 1000th box for ya, Don't Panic. Have fun finding it!
