The Archbishops of Canterbury and York, Dr Rowan Williams and Dr John Sentamu, are calling for 'good neighbours' - online and offline - to try out daily suggestions that will help create a safer and more pleasant environment in the real world this Lent.

The innovative campaign will use popular social networking websites and blogs to share actions to make the world a better place in small and simple ways. These range from leaving a thank-you note for the postie to going a whole day without gossiping.

Last year, more than 130,000 people joined in with Love Life Live Lent, launched by the Church of England to inspire, by text message, simple acts of service that spread happiness in our communities.

This year, daily suggestions are available not only through two colourful booklets produced by Church House Publishing, but also through social networking sites including Facebook, MySpace and photo-sharing website Flickr.

A group of prominent bloggers has also been enlisted to help spread the word through cyberspace. They include 'blogging bishop', the Rt Rev Alan Wilson, Bishop of Buckingham, and Dave Walker, creator of the popular 'CartoonChurch' website and blog.

Church leaders hope that the online social network group will help develop a community of 'Love Life Live Lenters' sharing their experience of following the daily suggestions. In return, Facebook will reward those completing three or more actions a week with the elements to 'build a neighbourhood' or 'grow a garden' on their profile.

The latest project is the Church of England's second initiative involving Facebook. Last Christmas, more than 2,500 users of the social networking site downloaded a special 'application' - sponsored by the Church of England - to send virtual Christmas cards to their friends.

Most of the actions of the Love Life Live Lent can be performed individually, while others require a group working together. They include spending a day trying to exist on just £1.40, the amount which more than half the world's population have to spend each day.

Other challenges include cooking or eating cuisine you have not tried before, finding out about volunteering in a prison or supporting prisoners' families, and discovering the names of your closest neighbours.

The Archbishops are commending the campaign, acknowledging in their joint foreword to the booklets: "For most of us, life is busy and pressured. It can be difficult to take time out to be with family and friends or to help to make our communities, local or global, clean and secure places of generosity. But Jesus calls us to love our neighbour as ourselves."

The full colour pocket-sized booklet comes in two versions - one for adults and 'youth', and one for children - each packed with 50 suggested actions to encourage people to be good neighbours.

Love Life Live Lent started life in the Diocese of Birmingham in 2006, inspired by a local pilgrimage. The booklet was such a hit that the original print run had to be increased repeatedly, and 70,000 copies were distributed through churches, schools and community centres.

The actions for this year start next Sunday, 3 February, and finish on Easter Sunday, 23 March.

There is also a Love Life Live Lent dedicated resource website, www.livelent.net, that features Bible study notes for adults, children's activities, and material for use in collective worship in schools, and a podcast available at www.chpublishing.co.uk featuring an interview with one of the original team behind the project, Canon Peter Howell-Jones, the Diocese of Birmingham's Director for Mission.
