The social networking giant has played the cautious this time and included from the outset, control over the visibility of this information adjusted default to "friends only".Users can include friends with whom they are, and the information will be published following the same system used for tagging photos. Once a place "tagged", it becomes permanent on Facebook, although it may be deleted by the user who posted first.

If a trade or business, its owner can reclaim his property.
