Erase request from sent by error
To erase a demand mistakenly sent to a person (e.g. ask for friendship) in the top menu go to "Configuration", then "Personal privacy settings".
Then write the full name of the person in the field "Block individual".
Then look it up and lock it. So not your friendship request, will be because obstructing someone removes any link with it. If you want this individual to find you or have contact with her, you return to the 'obstructed list' and eliminate it by pressing Erase (but already not your application will appear to him since it was previously obstructed).
This does not work for sent messages, considering that they are all saved in the Inbox of the person.
