Is there a way to see the date that classmates actually 1) created a profile and 2) registered?
With regard to registration date, I don't see it noted in their registration information when I click on their name from listed of registered attendees on Reunion Summary page.

I had been saving the email confirmations I received - for new profiles created and registration information, but then I lost my PC hard drive data (still with data recovery company).

thanks,
Rachael

You are correct, the date somebody joined your site is not displayed in their Profile. You, the Administrator, of course receive a registration email from any Classmate who joins, so you'd have the date that way. Although that's probably not too helpful if your hard drive is in the restoration shop....
