My submissions were rejected because of problems with something called a delimiter. What is that?
The character used as a delimiter in submissions sent to our mail server is called ‘pipe’ in computer jargon. On screen and on most keyboards it looks like a straight vertical line (“|”), though on some keyboards it looks like a colon made of two dashes instead of dots… This character is on the same key as the backslash character (“\”), i.e. you press the backslash key together with the Shift key to produce the pipe character. On most US keyboards this key is located and above the “enter” key, at the right end of the QWERTY row of characters. On some US keyboards the “enter” key is much larger, and the backspace/pipe key is smaller. On these keyboards, the pipe/backslash key is then located to the immediate left of the backspace key (to the right of the equals key). On non-english european keyboards the key is on the upper left corner, right below the Esc key and next to the “1” key. 4.
