HOW TO USE THIS PAGE
- 1. Select the proof P you want to put up as POTW.
- 2. Edit P to put this at the top:
- replacing <today> with today's date.
- 3. Edit the previous POTW to change:
- to:
{{Previous POTW| | }}
- 4. Edit this page to:
- (a) add the old POTW to the top of the list;
- (b) put the new POTW into the two places where the last one was.
