For classmates that send a check for their registration, I'd like to be able to post to their profile that they are coming to the reunion and/or send them a receipt. Is this possible? I have credit cards or checks as an option but am not quite sure how to show this when I receive a check without trying to log in as them and changing their password

Tina,

If you are using the event planner (which it looks like you are), when you receive a check, you can go to Event Planner, then "transactions" if they have already registered for the reunion and then EDIT next to their transaction, or "Register a Classmate" if they haven't registered yet. On their registration page, enter the amount that you received. I think it will ask if you want to send them a receipt when you save the changes.

Thank you!!!
