The people at CCC just announced presale dates for this year's congress:
"34C3 Presale" https://events.ccc.de/2017/08/09/34c3-presale/
"How the 34C3 presale works" https://tickets.events.ccc.de/34c3/docs/
I'm not a member of Brmlab, but I live in Prague and I imagine you'll
receive a batch of vouchers.
I'm writing you just in case the amount of vouchers you'll get should
exceed the number of people who are going: I would be interested in
getting one. Please let me know if there is any chance.
