If you're attending the conference, please add all the sessions you're planning to attend (including plenary sessions) to your own calendar in your office20.com Google Apps account. To do so, login to your office20.com Google Apps account (and logout from any other Google Apps account you might have), go to the conference's calendar, click on the session you want to add, then click on the "copy to my calendar" link. You can also click on the "Add to My Calendar" links from the conference's agenda, but links back to the sessions won't appear on your calendar (we're trying to fix this bug). Please make sure to add as many sessions as possible and to create "Busy" events for the time slots during which you won't be available in order for us to generate the most accurate heat maps, and the most relevant suggestions for meeting times when using the scheduling system.
