Erase request from sent by mistake
To erase a request wrongly sent to a person (e.g. ask for friendship) in the leading menu go to "Setup", then "Privacy settings".
Then write the full name of the individual in the field "Block person".
Then look it up and lock it. So not your friendship request, will be because obstructing someone removes any relate to it. If you want this person to discover you or have contact with her, you go back to the 'obstructed list' and remove it by pushing Erase (but currently not your application will appear to him since it was formerly obstructed).
This does not work for sent out messages, given that they are all stored in the Inbox of the person.
