Never signed up for Skype. Always had questions about its’ security.
If you check my posting history, I am Microsoft's biggest proponent. I'm an MCSA and longtime architect of Microsoft environments. That said, Skype is a steaming pile. Microsoft took the name and applied it to their Lync product, which was an office messaging tool. The old Skype you couldn't de-register or otherwise delete your account. Not sure about the new Skype.
