Abstract
We perform a crude computer simulation to show that no problematic black holes are formed by mergers in the early matter dominated phase of the HST models of inflation. These are black holes whose decays could have been seen as signals in the CMB. We also conclude that tiny "black hole galaxies" form. Since black hole decay products are mostly massive standard model particles, and perhaps their superpartners, the fate of these proto-galaxies is a complicated dynamical problem. It suggests the possibility of primordial structures on the order of the horizon size at the beginning of the radiation dominated era. This is about $10^9\ L_P$ in the current model.

Report
The paper is much better written now, and even though it does not give as self-contained a review of HST as I had asked for, it can be accepted. It is clear enough, and as I said in my previous report, it has some original ideas.
Recommendation
Publish (easily meets expectations and criteria for this Journal; among top 50%)
Report
One of the main concern with earlier version was that the paper was not very well written. Current version contains more detailed explanation and also addresses the concerns that were raised .
