there's some skype hack or whatever making rounds. if someone sends you a link that looks like it's going to a linkedin profile under your skype account name, don't click it. and be a good samaratin and let the person who sent it to you know their skype account has been hacked.
if you do click it or find you've been hacked in some way, type /remotelogout to force all alternate sessions to log out and then change your password.
