Some clients may not even offer or use the delete event. But even if they do, there isn't a guarantee the relays will.
True. I would like an edit though. High mileage eyes + fat thumbs = typos. LOL
I think it will become standard(if it's not already) that most all nodes will perform the action to edit/delete. Also it's possible to only post on those that do. But those things will all get sorted out eventually
