This has happened to me as well, except it involved the theft of my computer. I need the Skype IP address from where they modified my account. Please respond, Skype! Thank you.
I need to know that too, how can we see the IPs of last logins?
In Gmail, for example, is very easy and helpful to know if someone hacked your password.
Thank you very much.
