All looks good to me.

Couple of minor comments, and agree with @butlerpd 's first comment. But othe rthan that LGTM.

I think I've addressed everyone's comments. Please have a second look and merge if ready.

I think this can be merged. The comment on the final acknowledgment is relatively trivial and maybe we can wait till somebody comes up with better verbiage than I.

I do however have another suggestions, also probably for the future. Basically I'm thinking of adding incentives rather than asking for extra work. (more carrot and less stick)

As new versions of each package are released, calculation methods may change or be corrected.
To account for these calculation differences, please cite the version or versions you used to analyze your data.

I think we could point out that accounting for this differences would be critical for reproducibility which in principle is something the user is interested in (or feels they must do somehow). So .... we are providing a way to make it easy for them :-)

Suggested change to the citation works for me.

I think this should be merged now. This can easily be updated at any time.
