When the DSM-IV-TR (mental health manual) was due to be revised, a panel of experts first assessed all of the relevant research, and then put a draft proposal together. Then all interested parties (anyone, not just mental health workers) were invited to make comment, and finally these comments were reviewed, before the final thing was put together. If that can work across the globe, surely something similar can happen for a smaller organisation.
Maybe once this draft is through and accepted, RA-Aus could publish it with a comment section for future reviews, and if time permits, put the next draft out for comment.
