If you scroll down to the yellow block under the posting box, you can see which tags are allowed.
But wait, let me test it out, to make sure they all work, since I have never seen them used:
<blockquote>Blockquotes may come in handy!</blockquote>
Renders:
Blockquotes may come in handy!
Links are automatically rendered. I use no tag to show this link: http://www.pinside.com
However, the 'a' tag is allowed allowing you to do this
<a href="http://pinside.com">pinball</a>!
which renders this:
pinball!
We also have ul and ol with li:
<ul>
<li>List item a</li>
<li>List item b</li>
<li>List item c</li>
</ul>
Renders:
- List item a
- List item b
- List item c
But you could also use ol to get an ordered list.
Code can be done with backticks. If you're a coder you should be able to find that character:
This is some code
I hope it formats well
I have never felt the need for <b>bold</b> or <i>italics</i>.
But if there is a good reason to do so I would happily implement it for you!
