Monospaced Plain Text
"Monospaced text" is text in which every character has the same width. For example, the edit textbox on the wiki uses monospaced text. This kind of text is ideal for drawing diagrams (see the Crossbow article for an example). To insert monospaced text on the wiki, simply put a space at the beginning of a line. Here's an example:
This is monospaced text!
Be careful not to put spaces at the beginning of lines that you don't want monospaced!
