If you're already registered, you can log in and start scheduling sessions. https://www.wesconference.net/2009/scheduler/login.jsp
YOU MUST ARRIVE BEFORE THE SESSION BEGINS TO SECURE YOUR SEAT
Space may be limited, and empty seats will be given away three minutes prior to the session starting time. The My Scheduler Tool allows you to enroll in Breakout Sessions and BOF sessions.
Your enrollment will be validated onsite for these sessions.
Anyone not pre-enrolled may be asked to wait in a standby line.
You don’t need to schedule the Hands-on Labs or Conference General Sessions as admittance is on a first-come, first served basis.
Session times and rooms will be published in the online session catalog and the Mobile Guide prior to the Conference.
Mobile Guide. This tells me that Viigo (or something like it) will probably be used again for your WES Schedule.
Already scheduled the sessions I'm interested in attending.
EDIT: Okay, Viigo is doing the schedule again at Viigo
But the WES info didn't appear when I loaded the "I HAVE A CORPORATE IT POLICY" option. Uninstalled and did it again with "NORMAL BLACKBERRY" option, and now WES 2009 appears.
