TPAC 2019, early registration closing June 21

This year TPAC will be held 16–20 September 2019 in Fukuoka, Japan. During
that week the Web Application Security WG meetings are scheduled for
Tuesday and a half-day Thursday afternoon. Wednesday is the Technical
Plenary Day and evening reception.

Early-bird registration is closing soon (June 21). The current price of 102
Euros goes up to 151 Euros until the end of August. After that it's 200
Euros on-site (but still check in to reserve space first -- don't just show
up).
