In TranslateWiki there are three strings which refer to a non-existent preference for displaying (or not) the dashboard. These are leftover from copied Newcomer Homepage code and should be removed:

{
	"personal-dashboard-tab": "PersonalDashboard",
	"prefs-dashboard": "Personal personal dashboard features",
	"personal-dashboard-enable": "Display personal dashboard",
	"personal-dashboard-enable-preference": "To enable the personal dashboard, visit your {{int:prefs-dashboard}} settings in [[Special:Preferences#mw-prefsection-personal-dashboard|Preferences]]."
}

There is also a string, "tooltip-pt-dashboard": "{{GENDER:|Your}} personal dashboard", which we should be using for the mouseover tooltip for the Dashboard links in the personal tools menu in both Vector and Vector 2022, but is currently unused. In Vector 2022 the Dashboard tooltip currently reads "User menu".
