The 'Jubilee Time Capsule', run by the Royal Commonwealth Society, is collecting online memories of the Queen, to mark her Diamond Jubilee.
Sponsored by National Express, the idea is to get one memory for each day the Queen has been on the throne, throughout her 60 year reign.
92-year-old Eric Carter from Kidderminster is just one of the people who has taken part.
A former spitfire pilot, Eric met the Queen when he was one of two pilots chosen to accompany her on a state visit to Russia - the first since the revolution.
Although Eric is a keen internet user, organisers of the 'Jubilee Time Capsule' say that one of the challenges of the project, has been to get more elderly people involved, and are encouraging people to ask a family member or local librarian to help.
National Express say that the 'Jubilee Time Capsule' is the "world's biggest history project", and that thousands of people have contributed so far, including Prince Harry himself.

"We've been making and help create special memories for thousands of people across the years and this is an ideal project for us because in this fantastic year of national celebration we will be able to support what will become the biggest history project in the world."
