I asked about reporting gamma regression, especially whether to exponentiate
coefficients and what term to use if I did.

Joseph Coveney pointed to a couple of example from the literature that did
not exponentiate, and one that did.

Roger Newson advocates exponentiating and reporting them as arithmetic mean
ratios. At this point I don't quite understand, but I have clues where to
look.

Joseph Hilbe wrote me separtely and point out the identity of gamma
regression with a scale of one and exponential regression and advocated
taking tips on how to report from examples of exponential regression in the
literature.

At this point I don't quite understand the best approach, or what the
implications are, but I have clues where to look. Thanks, everyone.
