Charity Technology Trust has announced that many Microsoft products are now available to faith-based organisations through CTXchange, for just an admin charge. Microsoft had previously excluded such organisations. See CTT news item for further details.
CTT has also announced that Microsoft’s cloud solution, Office 365 for NonProfits, is now available for charities. CTT gives details at http://www.ctt.org/resource_centre/office_365_nonprofits, although it appears that you have to apply direct to Microsoft at http://www.microsoft.com/office365nonprofits.
