<pre> ... </pre>
This pair forces browsers to temporarily use a "fixed font", and preserves spaces. That is extremely helpful to rapidly create a simple table so columns don't get fussed up, since nearly all "reply boxes", such as FR, use fixed font. This gives a WYSIWYG situation without using the complex table formatting in HTML and is useful for simple tabular information.
Example columns for pre:
State Abbr. Wind Temperature New York NY windy cold Penn PA " cold Florida FL hurricanes nice Illinois Il calm warm
This is what it would have looked like without using pre./pre:
State Abbr. Wind Temperature
New York NY windy cold
Penn PA " cold
Florida FL hurricanes nice
Illinois Il calm warm
Good Suggestion! I’ll try to add that to the next one.
