After the massive success of the volunteer force at this year's Olympics, CSV is encouraging other Londoners to get involved.
"CSV Make a Difference Day is the perfect time for those inspired to volunteer by London 2012 Olympics with opportunities to do so, whether its designing a website for a local sports club, clearing out a nearby pond through to baking a cake or mowing a lawn for a disabled neighbour. In these tough times it is more important than ever for communities to come together and support one another through positive community action."
