Visiting the Smart.fm website you will notice that the service is announcing its migration to a new (old) site called iKnow!. Smart.fm will shut down on March 31st and does not take new registrations for that matter.
I have always been a big fan of the service although I never actively used it. And that seems to be one of the problems Smart.fm had, leading to the decision to turn the platform into a premium language learning service.
