Thanks for that. I actually started to write "I hope there's some in-built string translation utility" in my last post and then decided not to.
Those are two powerful features. And as you imply, the issue is not learning ModX as the site builder, so much as making it comprehensible to the end user. So those are some good tips.
It might motivate me to take another look once I find some more time. ModX has always been the CMS that I want to like, but nevertheless never quite take the plunge.
