Guys, I'm often disappointed with the questions I see here:

• Please check the official documentation first, because 3rd party tutorials often aren't accurate enough (albeit "might work").
• Please always check the error log when something doesn't work for you.
• Google Search is typically very helpful.
• Neuroscience has proven there's no learning without errors and correcting errors yourself the hard way. =)
• Try to make your questions challenging not boring.
