We would like the ability to publish/expire any content type in onMessage as well as select the publish and expire date/time that the content will appear and disappear so we don't need to manually add and remove it when we want it to actually show up and be removed.
When we were in NetCommunity we had the flexibility to select when content would publish and expire from our website and find that it is a step back to no longer have that option now.
You can already do this.
