Do you have an idea for a social web tool that can be used for social change? Submit it to Social Innovation Camp, an unconference/Barcamp like event in London April 4-6, 2008 that will bring together idea people, geeks, mentors and sponsors to build social web tools for social change in 48 hours.

To submit your idea for Social Innovation Camp, fill out their submission form and email it to ideas[@]sicamp[dot]org. To see what sort of ideas they are looking for, read their ideas criteria.

Submissions close on March 7, 2008. Their advisory board will select the ideas that they think have the greatest potential to benefit from the Social Innovation Camp weekend, and inform the folks who submitted the winning ideas by March 17, 2008.

Sounds like fun! Check out their Facebook group too.
