I'd say none of the above. No question is too stupid, someone generally at least asks for clarification, and sometimes I wonder how this site generates the "New Post" lists as sometimes I'll see many in the list. I answer a post and go back to the list and it's a lot shorter. Might have something to do with rolling over midnight; I don't know. As for your other post, I can say I was away for several days and didn't see it.
I think what you're supposed to do in these cases is add your own response to bring it back into the current list. I'd also add a post title (not to be confused with the question itself), bringing the lack of responses into focus in a polite way. I'd suggest closing this thread soon as I'm sure any answers to the first post will be found there and not here.
The more we hear silence, the more we begin to think about our value in this universe.
