The Big Give Christmas Challenge 2012 gets underway tomorrow at 10am, with the aim of doubling online donations to hundreds of charities to match pledges from the charities' major donors.
Arts & Business have joined with philanthropy website The Big Give to launch The Big Arts Give, a campaign to raise millions of pounds for arts organisations from individuals.
TheBigGive.org.uk is doubling donations to increase support for Haiti. Its emergency fund is doubling the first £500 of each donation made to the Haiti appeals on theBigGive.org.uk.
Major donor giving site The Big Give raised £7.7 million last week during its Christmas 2009 matched giving campaign. The first £3 million of this was raised in just two hours.
