There will be questions like that all the time. If no one knows a proper answer, they stay un-answered. Or a lot of homework questions don't get answered either. Sometimes people just don't have the answers, so they stay blank.
Does anyone else here have questions that don't have any answers yet and likely never will? cuz some questions are just there cuz no answer exists. i mean like questions like: does anyone know something with this and that. Sometimes what you are looking for just doesn't exist (yet). just look at some of my questions on my profile.
