Webinar Dates Confusion?

Am I going mad, or does the Xojo website state that the Introduction to Object-Oriented Programing 201 is tomorrow, but the first part - Introduction to Object-Oriented Programing 101 comes at a later date (5th August).

Surely part one comes before part 2???
I am now confused as to what webinar I will be watching tomorrow?

Can anyone shed some light on this matter?


The OOP 101 session was originally held on June 10th. There were audio troubles with it so the recording was never made available and thus I am repeating it next week.
