This community site specializes in helping churches gain a significant Internet presence through web sites and webcasting. A webcast can bring the Word to the homebound, those off at college, those on the other side of the globe, and show prospective pastors that your church has a will to survive. Help us make webcasting easier and more affordable for even the smallest churches by sharing your experience and knowledge with us.
