"If a single user is using then the account gets banned after a 30 days."
when you say lifetime you mean that when the account will be blocked after 30 days you will give the buyer new account?
what i am saying is usually the lynda single account gets banned after 30 days.
but mine will last a lifetime as there is a process for it.
so what i am saying is if the account gets banned after 30 days i give the money back.no questions asked.
