Another useful website is smartraveller created by the Australian Department of Foreign Affairs and Trade. It not only has general tips & advice for overseas travellers but also the most up-to-date information on the status of different countries as to their visa requirements, and safety issues due to possible health, natural disaster and terrorist threats etc.
Furthermore, it allows you to subscribe to their updates and register your travel plans. This could prove vital in the case of a major event overseas such as a riot or a tsunami allowing you to be contacted easily.
The mobile version of the website is really handy as it has all this information including each country’s embassy or consulate details right at your finger tips.
I guess it provides some peace-of-mind to family & friends.
