Does your church need an alternative to Microsoft PowerPoint? http://www.makeuseof.com/tag/7-free-powerpoint-alternatives-presentation-needs/ Note: It's been my personal experience that PowerPoint doesn't play well with other presentation programs. So if you choose to use any of these, I take no responsibility if your slides don't format properly at whatever church/auditorium/venue you choose to use them in. Libre, Zoho, and Google are the main culprits in this. Any of the programs that allow you to keep and show your presentations from the internet are an option, as you wouldn't run into any compatibility issues -- your only limiting factor is the internet connection required.
