Each Signatory review notice has a link to the document and a link to the comments page. Any comments you wish to make on the document should be added to the comments page.
Comments should only be made on the technical content. We do not expect our Signatories to be proof-readers and spot all the typos. Don’t worry we thoroughly review the document for these before making it into our final published PDF document.
You may notice that the document is a Google PDF and therefore it’s possible to leave comments on the PDF. However, we ask you do not leave comments on the PDF, but put them into the comments sheet only.
This ensures that we can track and reply to all comments as well as having a record of all comments for each document.
Friends of ZDHC (Brands and Vendors) are not full Signatories; therefore, they do not get all the benefits a full Signatory receives; this includes reviewing and commenting on ZDHC guidelines and guides.
