I'm pretty sure it wasn't a 'conference' but a meetup. Fairly regular events are SilverStripe meetups all around the world.
The UK meetup group have their own page - http://www.meetup.com/SilverStripeUK/ which you can follow and tag along too. Mostly the format for these as casual, show and tell events and discussion groups so much less formal than a conference.
