Thank you for putting this together Psychokiller1888. It's amazing to see this kind of organized content sharing is possible outside official channels.
I'm even more thankful for this as a model for use of Project Spark in an education/school setting. A SparkShare style server could be created on classroom or school located file server and kept internal to that school's network. It solves all kinds admin headaches and child privacy issues that the MS Project Spark server would have caused. Letting students have an internal-network and controlled shared project space.
