1) This can be found on the Club Administration' menu of the “Club Admin Page” which is accessible from either the main part of the screen
Hopefully, this page is self explanatory; if starting from scratch you will have perhaps only one (the current) president shown - if he or she has already been added as an officer - use the form top-right to add past presidents who are current members of the club - assuming you have already added them as members.
Note this list will stay short and easier to manage if you add all the current members that have been presidents BEFORE adding those who have left the club.
If adding members who have left the club, use the form bottom right. Deceased members will have an * displayed after their name automatically.
Past presidents are displayed in the public part of the website and also in your club handbook (if using the DMS facilities)
