Block Style: Flush left, no indent

This is an example of block style. Each line begins at the
left-hand side of the screen, and each paragraph is
followed by a blank line.

If your email program supports word wrap, you won't have to
worry about line length. The program will insert a carriage
return (CR) at the end of each line.

Some email programs, however, don't support word wrap, and
you have to insert the CR yourself. Whenever a line you are
typing reaches approx. 60 characters, hit the 'Return' (or
'Enter') key.

Whenever you come to the end of a paragraph, hit the Return
key two times to insert a blank line.
