The MySpace Impact initiative is intended to allow the social networking site's 10m UK users to support good causes by starting their own campaigns or raising money for a chosen charity directly from their profile page.
The launch of the scheme follows research carried out by MySpace, which showed that 16- to 24-year-olds are twice as likely as 25- to 40-year-olds to have volunteered for a charity or taken part in a sponsored activity in the past 12 months.
Similar MySpace schemes are already running in the US, Australia and Canada.
