(For now) Including a link to

It might also be worth noting that disabling your signature should be done when submitting an article. While I'm unsure if that's only an issue if you're previewing the article, when I was previewing my revised version of the Protection Paladin post the footnotes I had included were duplicated while I had my signature active. That fixed itself when I disabled my signature.
Also if you triple stack headers (So you get section 1.1.1 for example), the standard settings for the font becomes extremely small. You can work around this by using:
[/size="3"]======Example header======[/size]
There's also some quirks that putting any formatting tags within a header will cause the header to break.
