Erase request from sent out by error
To delete a request incorrectly sent to an individual (e.g. ask for relationship) in the leading menu go to "Setup", then "Personal privacy settings".
Then write the full name of the person in the field "Block person".
Then look it up and lock it. So not your relationship demand, will be given that blocking someone eliminates any link with it. If you desire this person to find you or have contact with her, you return to the 'obstructed list' and eliminate it by pushing Erase (however currently not your application will appear to him since it was previously obstructed).
This does not work for sent out messages, since they are all saved in the Inbox of the individual.
