Raaaid,im 1 of those silent types in the forum,ie i send a thank you when someone has posted and i tend to stay well clear of the silly comments!!
As you say you heard it 1st in EAW.I used to run an online Sqdn (No74Sqdn(V)RAF) and it was our No1 rule that if we got shot down(obviously it never happened to me much

) we automatically sent an S! to our victor.
It is a custome that has sadly slipped away.
Good Post by the wayu
S!
