Linking Out of Linkedin

I have Linkedout of Linkedin. The wretched thing sent an invitation to 'Linkin' to my entire address book. If you received such an invitation I am sorry.    I am also sorry for any reminders you get from Linkedin.    Linkedin seemed to be a good idea at the time but on this experience it is getting out of hand.  Heaven knows what Craven District Council, Northern Rail and Daily Telegraph Letters have made of my 'invitation'!
