Using ODK with PostGIS, GeoServer and Leaflet post is not working

Using ODK with PostGIS, GeoServer and Leaflet post is not working there neither http://geoserving.net/odk_geoserver. nor http://www.bryanmcbride.com/fun-with-the-open-data-kit or working i need fun-with-the-open-data-kit tutorial please help me

I don't think either of those websites are maintained by the OpenDataKit project. Are there particular resources you're looking for? Is this only a support request for those sites or is there some question you are trying to answer?
