@finner - you can only ever load replies when you are aware of their existence- you make others aware that a reply exists by sending them a notification- ...but you can only send notifications to others if you're aware they existany random replier cannot ever be aware of every interested party ahead-of-time, but replies usually end up on the (immediate) parent's host server because they are almost always explicitly sent there.it's not a spec or platform thing, it's a metaphysical issue
