We can't expect everyone to be on high alert on any email notification X days after having submitted something (this wasn't even detected by the buildbots afaik). And Daniel did end up responding here. Just frustrating when you have a problem and don't even know if the submitter has gone fishing for the next couple of weeks (and you can't even see who the notifications are sent to).

We should be more generous to new contributors, they will learn it sooner or later. And you don't necessarily wait for author's response before reverting it.
