Extend the time to delete my overlooked topic

My ability to delete this topic will expire after a few hours.  Some of my topics don't have any reply, so I'd like to post those topics again in case they were overlooked.  Please extend the expiry of being able to delete my own topics that don't have any reply.  (I don't want to add "clutter" by duplicating topics.)  Please also extend the expiry to delete my own replies and comments.
