Thanks for the prompt response! I'm sure I'm not the only person who was wondering about that, it would definitely be a good idea to mention that somewhere.
I can't seem to find any information about canceling a subscription once it's been ordered. Is there a FAQ or Help page that I missed? I'm interested in some of the premium files, but definitely not interested in getting involved with a service I can't easily unsubscribe from. Any info or directions...
