Whistle is a website: a combined directory, toolkit and
communication medium designed for politicians, for activists, for candidates and, most importantly, for the public. It's designed to cut through the arcane
trappings of the political establishment and make politics truly popular. It
helps people communicate with their MPs (through blogs, forums, and integration
with networks like Twitter and Facebook), create their own campaigns (using our
powerful proprietary tools) and support the causes that matter to them.
