!!!!! I caution you against the use of the exclamation mark, or "exclaimer". Children and teenagers use a lot of exclaimers. Immature writers also. A writer who uses too many exclamation marks causes them to lose their power. An exclamation mark should be used to convey shock or surprise. Use only one at a time, not !! or !!! or like some beginner-writers: !!!!!!!!!!!!!!! In a 1000 word article there could be, maybe, perhaps one use of an exclamation mark, but not any more, I would think. And only if something really deserves an exclamation mark. It's acceptable to write: He'd been shot! But it's a bit exaggerated to write: He picked up his fork! And yes, I know I use a lot of exclamation marks in my handwritten notes in red. I write in a casual manner, and my use of "+" or "&" instead of "and", or my liberal use of "!!!!!" doesn't mean YOU should do it. Certainly in writing a journalistic article, I would be wary of exclamation marks.
