What is the approval process we should use?
It is perhaps my own perfectionism as a writer that leads me to insist on hearing as many thoughts as possible. ;) In writing, it is often more important to hear what is most effective rather than what does not work. A writer will often agonise over the placement and use of each individual word before settling on a sentence. It is in my nature to be incredibly wary of how words will be interpreted, and this is what leads me to hope for a wider range of feedback.
I am aware, though, that others may see this as slightly obsessive. ;) I'm sure that any issues with wording or a guideline in general will be brought to the workgroup's attention so long as it is made clear that such criticisms are welcome and that there is an open and simple process with which to make amendments.
On the policy proposal, I feel somewhat confused, still. What you're suggesting is a separate page that outlines the method in which a guideline is suggested, approved or disapproved, and amended. That page is what the council must approve of for it to become official policy?
