What I would recommend the supporters of prof. Mills is less flame wars in discussions and more actual attempts for replication of his work at both theoretical, both experimental basis.
@Zephir: You shoot in the air I! I guess nobody here is a supporter of R. Mills in the sense as somebody is a supporter of a football team...
On the one side there is the Mill's Hydrino story and dense deuterium (Holmlid and others) on the other. If you like to discuss these phenomenas then either present or point to some calculations. Deep electron orbits are a fact and thus QM is at challenge (as it ever was since it's beginning!).
But the vast part of Mill's theory is not dealing with hydrinos! As long as the calculations of his orbit theory are confirmed by the experiments, they cannot be a priory wrong. As all theorys we know, it will certainly need some refinement, but this will never happen as long as QM is taught like a religion!
