Feautor is a free multi-lingual resource sharing site for Christian education materials. While the site particularly features resources from members of the Evangelical Lutheran Church of America, it is also open to others. Mary Hess was involved in setting it up. There are Bible studies, music, worship ideas, 'how to's', skits, meditations, retreat outlines, Lenten Studies, 'Sunday School' lesson series, stewardship resources, Bible scavenger hunts, pastroal care resources... Basically LOTS of stuff.
Well worth a visit.
