Idea

Well I have got some good news for you, I got an idea for what I should write about. This idea is very clever, and unique. This idea for my subject is... writing about a great idea. Well that was my idea for a subject, wasn't it great. O, I have a question for anybody, and that question is am I using wasn't it in the right way? Because for some reason the spell check says that I am spelling it wrong, so I took out the apostrophes, and then my sentence said, " was not it great" which to me does not make too much sense.
