The Salesforce London World Tour is 'sold out' but if you missed out then you can still attend after 1pm as Salesforce are accepting walk-ins on the day. If you can't be there but can get online then you can register to watch the event online here.
Assuming you are going then here are our handy hints...
There are a stack of events going on in and around the event. Visit the stands in the 'Campground' and no doubt you may get invited to an event or two. However, some are open for registration.
Finally, have a great time at the Salesforce London World Tour - we hope to see you there!
