Sorry about the lack of details right now, but I'm on my way out. Quickly, my church wants to start running a computer operated projector during church for announcements, songs, scriptures, and teaching. What are some musts? Are wireless projectors good? Our PC is about 80 feet from where the projector will be. I've heard of eworship. Is that good? What do you guys use? You may have told me already, but please refresh my memory.
