Perhaps you have followed key events in history with the BBC. Where were you listening when the Berlin Wall came down? What were you doing when Nelson Mandela walked to freedom? How did you hear about 9/11?

Perhaps you have moved away and keep in touch with events at home by your favourite programmes? Have you ever lost contact with someone only to hear them appear on the BBC? Has one of our lifeline programmes re-united you and your family?

Global Live! will link up the world and connect people who matter to each other. Contact us with your stories and share them with the world. We especially want to hear from families whose members are spread throughout the world. Let us know your story, and be re-united on Global Live!

Send your stories and contact details to us using the form below. We will get in touch with you about taking part in Global Live!, which will be broadcast on the BBC World Service on 19th December at 1630GMT
