It is not too late to contribute to the brilliant 'History Matters' mass blog project; in fact you have until November 1st to claim your place in history.
The project involves writing a diary about your day today (October 17th) and uploading it to the History Matters website: http://www.historymatters.org.uk .
Anyone in the world is welcome to do it. The resulting 'mass blog' will eventually be stored at the British Library for reading by people in the future (how ever long that lasts).
Who knows, one day people could be reading about your day on Planet Earth today at the other end of the universe.
