Sulako gets my vote for one of the most useful, and accurate posts I have ever seen on PPRuNe! Well done! Everyone else.... Listen up!
I see two opposing comments about the use of English, and both have merit. Though perhaps challenging for race never ends, do realize that on PPRuNe your ONLY means of presenting yourself as worthy of consideration, is your demonstration of precision and accuracy, which you will have to do by writing well. Those people who might consider you for employment in the future, will look for those qualities in you, to judge if you will apply them in everything you do, including your flying, and customer satisfaction. Don't set off on the wrong foot with them, because of careless writing, or use of English.
