I've seen people discussing and attempting various dialects and accents in the two days I've been here, so I thought this resource might be helpful to everyone;

So it's exclusively dialects and accents of English. Go to any country anywhere on earth and you'll be hearing their accent when speaking English. Of course, their collections of dialects of English speakers are more rich with samples than their collections of foreign speakers. However, there's two Norwegian samples for Nords and anything else you might want to attempt.
It's helpful to listen carefully to samples before attempting a dialect or accent yourself. It's also helpful to learn phonetics and I can recommend books, but that's a much weightier endeavor so I'll just tell that to whoever asks.
