Lol! Well you've certainly passed in terms of attention to detail Cladosporangium
(its not something I would normally notice).
From what I've seen, PPRuNe is home to a variety of cyberactive mysteries .. one of them was the 'Time Stamp Fairy' which scattered everyone's posts at random throughout an existing thread so that you might find your current post placed on page 2 of an 80 page thread. That was great fun!
There are doubtless many other anomalies to which PPRuNe is host and my guess is that we are just beginning to discover them!
