I was just asked to do morning prayer at our Presbytery meeting this weekend ( as a late replacement).
I decided that I would use PowerPoint for one of the hymns (since it is in a yet-to-be released hymn book supplement, luckily the composer will be there to teach it). Then as I was working on that I decided to do the whole service on PowerPoint. Kept it simple since I have never played with the program before. But I can easily see how doing that regularly could eat up loads and loads of time.
FUn, but still...lots of time to play and get it "just right"
