Add editing to ArcGIS.com social media map template

[GinaKiani]

Hello
I made a web application through ArcGIS.com using the social media template and would like to add editing capabilities to one of the layers (CultureAndCommunity)
The map application can be seen here:
http://uscssi.maps.arcgis.com/apps/S...62705e211f8267

The layer I am trying to allow editing features for is here:
http://services1.arcgis.com/ZIL9uO23...eatureServer/0

As seen in this layer by itself, I have published it from arcGIS desktop with the editing features enabled
I appreciate any help or direction at all in allowing users to be able to add features to this layer or edit the attributes of the layer

Thanks so much!!
