Twitter will allow its 200 million active users to reminisce - or perhaps cringe - as it starts sending out its entire archive of messages.
To begin with, only English-language users will have access to the service. But eventually Twitter will send a download link containing your full personal archive in just one file to any user who asks.
Twitter Executive Chairman Jack Dorsey brought the service to life on March 21 2006.
400 million tweets are sent worldwide everyday.
