If you liked this article, I'd be incredibly grateful if you tweeted about it.

Also, I don't send emails often but when I do, I try to fill them full of useful goodies. If you like code snippets & dev tips, join my mailing list. There's no catch but I'll probably want to tell you about any new plugins & tools I build.
