As Off The Ball's Nathan Murphy said tonight on our Newsround, England's rugby authorities could have added an extra bullet point to their social guidelines for players at the upcoming World Cup: "They should have had a 25th point ... don't tell anybody about this!"

With the tournament on the horizon, England's Rugby Football Union has come up with a 24-point guideline governing social media use, which The Telegraph were able to get their hands. It includes lines such as "engaging in a public Twitter argument is a battle you won’t win".

And here's the Top 5 social media do's and don't revealed by the paper: 

1. Do not post when you are in a bad mood or immediately after a tough loss.

2. Fans of other teams or other players may try to provoke you via social media. Do not react to this.

3. Do not post pictures of drinking, smoking, nudity or while driving – that is illegal.

4. If you enjoy a good win or achieve a personal milestone, take 30 seconds to tweet a "thank you" to the fans who were there to cheer for you or support you online.

5. Share photos when the team takes part in community projects and any other interesting insights into your life as a professional rugby player, but be mindful of private team areas which should not be shown to the public (i.e the performance centre).
