From your last posting I now take it you're a controller? (CR removes second set of blinkers). Nice user-name - that makes sense now too.
Yep, we're all (mostly) friends here!
I had pictured you at the sharp end of a busy flightdeck on my first, quick reading. As for myself, I am closer to the bugsmashing end of the industry (ie I sit in one...) There's not much to play with in most of 'em, and plenty of time to talk (which doesn't mean you should say more than required, before I get jumped on!
)
I agree, change for it's own sake is not helpful, and callsign at the end fits that IMHO.
CR.
