"Tickets will go on sale June 20th at 10am!" Surely it's not 10am GMT. Anyone knows the time zone of the referred 10am?

They're already on sale, bought mine earlier so I'm guessing they meant GMT. Would make sense given that the event is on in London.

Hate to be that guy, but UK is in BST now which is GMT+1 :-)

What time does it start and end? Trying to see if I can fly in and out on the Saturday or if I'll need to stay over.

I agree, this would be very useful information to know.

Good initiative, and good excuse to visit London :) +1

Sold out :(

You can always implement your own and start a conference as well:
