Tsan, Did you make sure you are logged into your ArcGIS online account within ArcGIS Explorer? Once ArcGIS Desktop is open, click the ArcGIS Explroer Desktop Icon , then click "Sign In". Once signed in you can search for your map in the search window and it should open up with the layers that are in your map. (I just tested it and it worked). You also find some more information here.

You are right, at the moment you can only collect point data. I'm sure somebody on this forum could help you with a python script that downloads your data and from there you can run everything you need in ArcGIS Desktop (models and such) and then use the script in this thread to upload your data. Eventually you can automate all that. ... View more

David, When you talk about customizable fields what do you exactly mean? Before you upload the feature service through ArcGIS Desktop, you can create domains in a geodatabase and assign them to your feature service attribute fields. Once you upload this, your user will have dropdown boxes and don't need to manually type in data which reduces error. I don't know if that is what you are talking about, but I hope this helps at least a bit. Tim ... View more
