More power to him. Broadening one's horizons is a good thing.
As far as civility, in all candor have to say I don't expect it. He and I have managed to be mutually civil for several years now, after some bouts of the typical, nasty flame-throwing back at glocktalk.
I don't know the "why" of it, but while he's been (mostly) civil to me, he seems unwilling to do the same with some others; some of which seem to have really tried to do so. Don't know why, but it's none of my business, and no skin off my nose.
JD if you read this, you know I'm not lying.
