Auto fill registration form from previous registration form

Can information for event registration be saved to use again the next time a user fills out a registration form or another event/class, such as Names, Addresses, kids names? Is there a user profile form or member profile management widget or app?

Unfortunately, we do not have a widget or app that can do what you're trying to accomplish. However, if you already collected the data for the event and you transfer the data to Excel Spreadsheet, you can use the Spreadsheet to JotForm widget to autofill or populate fields from Spreadsheet.
