I'm looking for where to edit the text that gets sent to users who pay by check.

Right now...
PAYMENT DETAILS:
Payment Method:   Check
PAYMENT INSTRUCTIONS:
Please make check payable to:

Mail to: blah

I'd like to change the name of the reunion to a person's name. Does anyone know where the settings are to change this?

Go to the Reunion Planner, scroll down to the "Payment Types Accepted:" section. There you will see the "Make checks payable to" input field.

Thanks!
