How do I generate an attendance report?

I am trying to go back to a meeting that my group held last Friday into Saturday and generate an attendance report.  I have seen Poll Reports and Registration Reports, but since we do not conduct polls or ask for registration, those reports are empty.  I do not see options to generate an Attendance Report.  Is there a switch I need to enable, or something else I need to do so that I can generate this report?

The account that I have through work DOES let me generate an attendance report. Are there different kinds of accounts that don't allow such a report?

Thank you
