The Every Man Remembered initiative, run by Poppyscotland, the Royal British Legion and the Commonwealth War Graves Commission (CWGC), aims to keep alive the memory of each of the 1,117,077 people in the armed forces who died in the 1914-1918 war.
The four-year project, launched yesterday to mark the 100th anniversary of the war's outbreak, was inspired by a 14-year-old schoolboy who visited a war cemetery in Belgium and wrote to the Legion asking why some of the graves had dozens of poppies and crosses next to them while others had none.
He said: "I know that not everyone can be remembered as an individual but I felt it was a shame for some people to have dozens of poppies and crosses while others had no-one left to remember them."
Now a website has been developed, linking to the official CWGC database, which contains records of men and women from the Commonwealth who died during the war and allows people to pay tribute to someone they have a connection with or find someone who has nobody to commemorate them.
Information on the person they have chosen to remember can be viewed and they can make a dedication.
Anyone in Scotland taking part will have the opportunity to make a donation to support Poppyscotland.
More than 70,000 Poppyscotland supporters have been sent an invitation to commemorate a fallen serviceman or woman.
