Friday November 21 is the 40th anniversary of the Birmingham pub bombings
, an event that traumatised a city, ended the lives of 21 Brummies and injured hundreds more.
As time passes, the city's memories might be fading, but not the sense of injustice felt by the victims' families, who are still waiting for justice.
After the wrongful conviction of the Birmingham Six was overturned, no-one has been brought to justice and punished for this atrocity.
The Birmingham Mail has been campaigning solidly
for a new inquiry into the bombings, and as the anniversary approaches, we want to bring this forgotten crime back to the forefront of the thoughts of Brummies and the whole country.
Please help us by backing our innovative and powerful social media initiative, which is a real first for a media campaign of this type.
At the precise moment the first bomb went off 40 years ago, your Facebook and Twitter accounts will publish a simple message of commemoration for the victims, with a call for an inquiry. Your message will be published simultaneously with those of everyone else who has also signed up.
You can be part of an extraordinary moment which will show the families that their loss and suffering hasn't been forgotten - and it may even help persuade the government to open an inquiry.
