writing below. "Revenue management is a significant and permanent issue for our company, and we consider it's important to seek the best solution at all times." And all of the three replies that I received pointed out, "it's is incorrect," and replaced it with it is.According to any dictionary that I have, I believe "it's" is just simply the shortened form of "it is." But at the same time, because three out of three people corrected the same thing (all of them are native in English), I think there should be some tricky grammar, which I don't k ow. Could anyone please explain why "it's" is not okay, and what kind of grammar that is.Thank you in advance, M As far as grammetical guidelines that It's only use while speaking and It is only use while writting an Essay,Paragraph,application vice versa. I hope it would highly be acceptable my point. *Usenet post removal: Use 'X-No-Archive' or please send proof of the poster's email, we will remove immediately.
