I guess there are two ways to look at it - either these are coding style guidelines, or they are authoritative coding style rules. My impression was the former, that they were guidelines, and as such I think the Guide is the right place for them. If these are to be treated as authoritative rules however I agree, the Guide is not the place for them. In that case we should make sure these are published in the right place asap and just have the Guide link to them.

What would be the right place to put coding style rules? Can we put it in the "parent drawer" of the Guide, next to the bylaws, census, etc?

Thanks,
