## Key Takeaways

💡 **Remember:** Participant Kit is smart - it knows when someone's already been sent a form and will let them update their existing response

🧪 **Try:** Use in-person signing for participants who show up without consent - get the unique link from their profile

⚠️ **Watch for:** The in-person link only works when you're logged into Participant Kit - have your device ready before the session

⚡ **Quick tip:** Resending a consent form works for both reminders and corrections - participants can fix mistakes on their original submission
