The British Embassy has introduced a new on-line registration for those travelling abroad and those living abroad.
It seems a very good way for the Embassy to locate relatives etc in case of an emergency.
Only probem I came across was that the entry is only for 366 days, therefore it needs to be updated once a year for those living in Thailand.

"Use our new LOCATE service to tell us where youтАЩre travelling to so our embassy and crisis staff can provide better assistance in an emergency such as a tsunami or terrorist attack.

It only takes a few minutes to register your contact details and travel plans online and the local British embassy will know youтАЩre coming. There's no need to contact them directly.

Going on another trip? Simply, login and update your Locate account and weтАЩll let the next British embassy know."
