I was hoping to just kiboz[0] him.

For real though he does have a habit of showing up when mentioned even if there isn't an real @mention mechanism.

He has also confirmed that one should send an email rather than @dang-ing.

I'm sure he'd prefer that, but doing so would associate my email with my username (which I'd prefer to avoid), and it was demonstrably unnecessary, at least in this case.
