Either way, going back to the original question he raised, nobody is ever required to respond to a PM and it's unreasonable to act as though you think you're entitled to receive a reply, regardless of whether the PM was sent to one user or to a large group.
Edited to add: BTW, I wouldn't normally post a PM publicly because I view that as a bit of a faux pas since, well, it's a private or personal message. But I feel like he's more or less waived that via his comments in this thread, so for those who didn't receive the PM in question and might be wondering, this is the one I got (along with the other people I mentioned before). Don't know whether it's identical to what froggie and others received. My reply is below his message.
How do you register on Highway Divides? Because every time i hit the register button, i get "This page isn't working". Any suggestions? Thanks.

Sorry, I have no idea what you’re talking about—don’t know what Highway Divides is.
