We got our first online STP pledge this week but then I realized that there appears to be no way to find out who the pledge is from unless they put their full name in the "Display Name" field on the pledge form.

The instructions under the Display Name field say:

Enter your name (up to 20 characters) as you would like it displayed on the public page of the person/team you are sponsoring. If you would rather remain anonymous, enter Anonymous in this field; however note that your real name will still be displayed to the owner of the page.

It doesn't appear that this is happening. I want to be sure that I know who supported us so that we can send them thank you notes...
