Yesterday, I asked a question that was almost immediately closed as "not a real question". I don't really agree with that assessment, but I'm also not an expert on what qualifies as a real question here.
Anyway, since then I've done some more research and have found a few answers. I'd like to be able to add them for posterity so that others with a similar question could find them, but it seems one can't answer a closed question. Is there a way around that?
I also wondered if closed questions are "hidden" from search engines, in which case there'd be no sense in adding answers for posterity, but that doesn't seem to be the case.
