The only problem you'll end up having is that you'll double-book a few sessions that are happening at the same time. Unfortunately, that's just the way it is with these events. During last year's conference, we were able to install a WES version of Viigo and connect back to our WES online schedule to get an RSS feed of our events. Quite nifty and we don't have to rely on our calendar (although I used both).
In the beginning the Universe was created. This has made a lot of people very angry and is widely regarded as a bad move.
