Erase request from sent out by error
To erase a request wrongly sent out to an individual (e.g. demand for relationship) in the leading menu go to "Configuration", then "Privacy settings".
Then write the complete name of the person in the field "Block individual".
Then look it up and lock it. So not your friendship request, will be given that blocking someone removes any relate to it. If you desire this person to find you or have contact with her, you go back to the 'obstructed list' and eliminate it by pushing Erase (but already not your application will appear to him since it was previously blocked).
This does not work for sent messages, because they are all stored in the Inbox of the individual.
