Guardian crowd sourcing policy ideas for the mayoral contest

From Dave Hill's "Metropolitan Lines" email:

"Coming up: special announcement

From Monday for two weeks the Guardian will be inviting its readers to participate in a unique crowdsourcing project about London and its forthcoming mayoral election.

Each day at Comment is free and my London blog I'll be inviting you to contribute policy ideas to our very own Manifesto for a Model Mayor, which will be published in e-book form by the end of the month.

An article telling you more about this exciting exercise in Guardian open journalism will appear on Sunday morning at 11.00. The aim is to paint a picture of a dream mayoral candidate and the policies to bring his or her vision for the capital to life. What sort of London do want a mayor to help build? Get thinking now. We need your help!"
