Don't feel apologetic about using the ICAO or IATA codes, after all this is a "Professional Pilots Rumour Network".
Sure. And there are professional pilots on this forum who have nothing whatever to do with airline operations (anymore), other than to ride as a passenger from time to time. It's fair enough to use codes in the discussion when most people understand the context. Using a code in the opening title of the thread will send some people to Google, where simply writing the three extra letters would have let everyone understand from the beginning without distracting the effort with a google search.
For those times I fly as a crew member (knowing that most of my professional piloting is solo), the pre takeoff briefing will include: "Is that understood?" meaning that the pilot preforming the briefing would like to assure understanding with the crew. I hope that professional effort toward effective communication can extend to posts, or at least the titles....
