ExpoSong is a project to create a free, worship presentation software. It's early in development, but be looking forward to seeing some nice features in the program.
Our company will be providing support for that as the project grows. If you're interested in using the project, but need some technical support, we may eventually have the resources to come to your church, install the software, and train those that will be operating it.
It's still an early project, but will hopefully grow to become a powerful piece of software to empower churches to provide overhead text, lyrics, and more in the future without the expensive costs of commercial products.
