You're in luck, because he wants to meet with you too. Oprah and Stephen Colbert have been trying to book him for months, but Glen keeps putting them off. He's just not into that scene. You, however, he has time for.
First, click on the date you want to meet on the calendar at the top-right. Then click on the time you want your meeting to start. A pop-up will appear so you can fill in the details of the meeting. Click the "Save" button at the bottom of the pop-up. If everything works correctly, you will receive a confirmation email. If you do not receive an email, the appointment was not created!
This tool is for scheduling appointments in advance. If you need to meet now-ish, it's probably better to call Glen on his cell: 650-380-0896.
