Just an update: as of today (3.11) only 59 seats are still available! Hurry up so you won't miss it!
At this moment all 100 tickets for the user group are all gone. Due to limited capacity at Adidas we are not able to increase the number of seats avialable. There is a sizable waiting list on the eventbrite page, so can still sign up for a (very slim) chance of some seat opening up for you.
Thanks everyone for the enthusiasm, we are really looking forward to this user group and this gives us a lot of positive energy to keep organizing these.
