Editor's Corner

If you are a Facebook fan, Twitter fanatic, e-mail aficionado, or tend to get excited when you are communicating with others, you may be familiar with the use of more than one exclamation point (!). Somebody asked me, “When is it okay to use more than one exclamation point at the end of a sentence?”

The nice answer:

The Chicago Manual of Style tells us: “An exclamation point (which should be used sparingly to be effective) marks an outcry or an emphatic or ironic comment.” [KC – Note the article here: An exclamation point. One. Singular. Alone. Uno. Un. Έʋα.
Ein.]

My answer:

Never!

I won’t be as cruel as some who say “a person’s sanity is inversely proportional to the number of exclamation marks they use!” (http://wiki.lspace.org/wiki/Multiple_exclamation_marks), but I will say again that you only need one at the end of a sentence. The only time you should see an exclamation point in technical material is when you are writing about a warning or error that displays in the software.
