Labeling in ArcGIS for Server

I have had a really difficult time labelling features in ArcGIS for server over the years. I have even had to resort to creating a new labelling layer and adding it as a new service and adding it to my online map. However, this spring I actually figured out that if I use the python option to label my fields in ArcGIS desktop and publish the results onto ArcGIS for server, the labels will be published (along with the scale dependencies chosen).
