Is my question too specialised?

I didn't get any answers or comments to my question. On reflection, I wondered whether I made a mistake by talking about MCMCglmm, which as far as I can tell is not a well known R package, and probably isn't cucial to my question. Should I perhaps re-write it to simply say:

1. I have used multiple imputation to obtain a number of completed datasets
2. I have used Bayesian methods on each of the completed datasets to obtain posterior distributions for a parameter (a random effect).

How can I combine / pool the results for this parameter ?

Or would this be too vague ? Please advise how I can improve my question.

If your concerned about MCMCglmm scaring people off, I would suggest changing your title, perhaps something along the lines of How can I pool posterior means and credible intervals after multiple imputation?
