for line break, use <br>

for paragraph, use <p>

for indention, use <blockquote>Your text here</blockquote>

<b>Bold</b> = Bold

<i>Italics</i> = Italics

<u>Underline</u> = Underline

<a href="http://linkfilter.net/">Linkfilter</a> = Linkfilter

<img src="http://website.com/pic.jpg"> =

resize it using: <img src="http://website.com/pic.jpg" height="15" width="15"> =

If you want ASCII art, use this: <pre>Preformatted Text</pre>

example:

 .----.                             .---.
'---,  `._________________________.'  _  `.
     )   _________________________   <_>  :
.---'  .'                         `.     .'
 `----'                             `---'
