The FPish messages use an HTML-like markup language to include elements such as code snippets, images or links. These are the tags you can use:
<b>This syntax</b> inserts bold text.
<i>This syntax</i> inserts italic text.
<c>This syntax</c> inserts inline code.
<s>This syntax</s> inserts strikethrough text.
<h1>This syntax</h1> inserts a header. Available header tags are <h1>, <h2>, <h3> and <h4>.
<code>...</code> inserts a code snippet, like this:
main = putStrLn "This is a code snippet."
<code lang="fsharp">...</code> specifies the programming language, providing syntax higlighting:
let main() =
printfn "This is an F# code snippet."
<a href="http://fpish.net">this syntax</a> inserts a link to FPish.net.
<img src="http://fpish.net/images/fish.png"> inserts an image.

You can insert ordered and unordered listings. They are identical to their HTML counterparts.
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul> | becomes | |
<ol>
<li>Item 1</li>
<li>Item 2</li>
</ol> | becomes | - Item 1
- Item 2
|
You can quote another post using <quote>...</quote>.
This is some nice code.
I quite agree with you.
You can add tables using HTML's <table>, <tr> and <td>.
<table>
<tr>
<td>C1</td>
<td>C2</td>
</tr><tr>
<td>C3</td>
<td>C4</td>
</tr>
</table> | becomes | |
