[R-sig-ME] MCMCglmm ordinal model

[Frank Lawrence]

When I specify an ordinal single level model using MCMCglmm, part of the output includes estimates for the cut points for the response variable scale. Two questions:
1. Is the "post.mean" on the original ordinal scale or do the estimates need to be exponentiated like the coefficients? 
2. Why do I occasionally wind up with fewer cut points than the number that existed on the observed variable?
