Versions

A new version when the text changes, and who is asked again

The first save of a text makes version 1. Later, saving a changed title, text or checkbox label asks Ask everyone again?:

Answer	What happens
Ask everyone again	The text becomes a new version, and every user accepts it again at their next request
Keep as a correction	The current version is rewritten, such as for a typo; no one is asked again

The Versions tab lists every version, the latest first, with its Version, Title, Text, Checkbox, who published it (Published by), when (Published) and how many users accepted it (Acceptances).
