How to write a draft1. Write a proposal

• Describe in a MSWord document a list of “instructions to the editor” (aka “draft normative text”). For whole new sections, this will be 100% new text/figures.

• Create Powerpoint presentation based on above to describe salient details2. Submit both docs to server at least 4 session hours before intent to

vote on proposal• The “4-hour rule” is part of 802.11 rules and is strenuously enforced• Why? It gives people time to read, understand and consider the proposal• TGT can also rule that longer period of time is required• Helpful to announce existence of the documents through the reflector

3. Make presentation before the group4. Make motion to accept proposal (the “draft normative text”) into the

draft• 75% majority required for any changes to a draft

(additions/changes/deletions)• If approved by group, editor will incorporate into the draft

Submission

Another way to write a draft

• Have an open discussion of some aspect of the draft

• Ask editor if the direction is clear• If answer is “yes,” editor is empowered to make

the necessary changes– Approve by a vote the outcome, expressed as a written

motion

►Both methods are acceptable under the right circumstances!
