[R-sig-ME] Failing to understand effect of centering a predictor in multilevel model

[Steve Candy]

If my memory serves me correctly when in checked this out with a simple
random slopes, random intercept model on a single predictor, say x,
centering x changed the correlation between the random effects quite
dramatically but nothing else compared to the lmer with uncentered x.
