Okay, so I've gone over how to post pictures in Markdown and BBCode, and a couple of you have said that it'd be nice if I went over some of the most common functions for creating post formatting here.
This post will discuss hyperlinking and embedding pictures in Markdown, and a few other neat little tricks to make your posts look better or generally stand out more.
From Daring Fireball: Markdown Basics --
Markdown offers two styles of headers: Setext and atx. Setext-style headers for
<h2>are created by “underlining” with equal signs (=) and hyphens (-), respectively. To create an atx-style header, you put 1-6 hash marks (#) at the beginning of the line — the number of hashes equals the resulting HTML header level.
Blockquotes are indicated using email-style ‘>’ angle brackets, as I did to show you the previous quote.
