Even though email has existed for many years now, I still receive from time to time submissions that are typed in all capital letters.
Early on, those on the Internet would reply to these with “Why are you shouting?”
I won’t do that, but all capital letters do pose a problem.
What I will do if the submissions are intended for letters to the editor, I will retype the ones that are a sentence or two in length.
The very long ones I simply delete. There is not enough time in the day to retype submissions of this kind.
On the other side of the coin, I occasionally get submissions that are in all lower case letters.
These are much easier to fix and usually make it into Numismatic News.
I do not expect every submission to look like it came from an English teacher. There is a certain amount of editing that I am happy to give anyone, but deadlines do limit this attention.
