Is there a widget I can add to my dashboard in eServices to remind me of my CPPT expiration timeframe?

Yes! Head to eServices, and then click on the gears in the right corner. Scroll down to Widgets, and click on "Add New Widget" then click on "My Expirations" and hit save. When you go back to your dashboard, you'll see the a My Expirations box, that will populate when your CPPT expires within 90 days. You'll also receive email reminders.
