The Sheila McKechnie Foundation has launched a website offering free resources for charities and community groups that want to lobby for change.
Campaign Central provides free guidance for campaigners on topics such as how to use the media and how to stay within the law. There is also an online community to enable charities involved in campaigning to discuss their work.
A spokesman for the foundation, which provides training and support for campaigners, said the website cost £20,000 to develop and was funded by grants from the Baring Foundation and the Joseph Rowntree Reform Trust.
Linda Butcher, chief executive of the Sheila McKechnie Foundation, said: "Campaigners are a key part of our democracy, challenging policy makers and the public to see and do things differently."
She said she hoped the site would become a key resource for the sector. "Just like a presence on MySpace is important for bands trying to make it big, Campaign Central is the natural home for campaigners to network with others to build a movement," she said.
