There is no official training program for TntMPD. Your specific ministry might offer training. Look for some up and coming “Handy Reference Guides” on some key features and topics to help users make the most of those specific issues without consulting the full user guide. The most comprehensive resource is Exploding TntMPD, which covers all but the most technical features of TntMPD.
The latest version of Exploding TntMPD is always available on the TntMPD website. If you want a printed version but don’t want to use your own printer, you can email the file to a local print shop such as FedEx Kinko's and they can print and bind it for you.
No. There is currently no one available to offer phone support at this time. If you sense God leading you to help develop a customer support team for TntMPD, many people will thank you.
