The document currently resides at https://github.com/tdwg/dwc/blob/master/.github/CONTRIBUTING.md. Would it be better at https://github.com/tdwg/dwc?

I agree that there should be a reference to the VMS, but is this really the place to say what is normative in the standard?

I would recommend against adding anything about amending term_versions.csv.

I set up two issue templates, one for new term requests and one for term change requests.

If I can get consensus I'll proceed to make the changes.

Partial changes made to match issue templates in 551c64e

With respect to the usage comments, we might indicate that they are optional and only necessary if the definition does not provide all of the needed information about how the term should be used. I don't know how to say that in a way that is not too wordy and suitable for a form.

A lot of this content is in the FAQ, which was created primarily for the latest public review. We should have a strategy for merging and placing this material. Best in an .md file for consistency probably. Recommendations welcome.

Updated the contributing guide and integrated the Wiki FAQ with it.
