If you’d like to customize these preferences, to create personal user (browser) preferences, make a copy of this page somewhere, preferably as Profiles.insert_your_name_here-Preferences, edit that page with your new preferred settings,
and then select Set Preferences of this Page on the page containing your newly created settings.
This sets a cookie on your browser which tells PmWiki where to find your personal preference settings.
