All Groups: The web is absolutely stuffed with fascinating educational videos on every subject imaginable. No Internet connection where you meet? No matter - these videos are easily downloaded to a laptop to be played back and projected later onto a screen or a convenient wall.
The software to do this is 'Replay Media Catcher' and in the opinion of this writer every local group should have it as well as the digital projector that turns every home or hall into a private cinema. Both software and hardware are well worth the purchase price.
