Hey! Nobody steal your reminder list.
If you happen to find that your reminder list was disappeared from your QuickBooks home page (Dashboard) it could be someone had accidentally turned it off.
To turn on your reminder list, you can simply go to edit menu and select Preferences. In the Preferences window, select the Reminder Preferences. Reminder list is a personal preference setting, so it will be under your Personal Preferences tab.
Since it is a personal preference, every user who requires this feature has to turn it on manually.
