Prince Charles is using MySpace to raise awareness of his Prince of Wales Rainforest Project, urging the social network's community to electronically sign a petition to fight climate change by addressing rainforest destruction.
The majority of the people interviewed for the Brand Republic video thought that it was a good move by the Prince because it was an effective way of raising awareness of a good cause.
Many also said that it showed that he was more up to date than he used to be and more "with it".
However a couple of people disagreed claiming that MySpace was "three years ago" and that he should join Twitter or Facebook instead.

In the video, Prince Charles said: "One of the internet's great strengths is that it can enable diverse communities to come together to ensure that everybody's views and actions can really be made to count.
"It provides the potential to create global determination for change on a vitally important issue."
