If new services are added, will they be available to existing customers as part of their existing services, or will there be additional charges?

All new services added would be available for you to use. If such a service would require a new contract between you and IndieMassive (such as a publishing agreement), this would require us to enter into such discussions, but there would be no additional charge for you alongside your distribution agreement. We really mean it when we say zero hidden fees!
