If you have received an invitation by official means, you are welcome to the 2017 edition of AlligatorCon Europe. If you've been here last year, you know the drill – friendly hackers, free booze, no-nonsense technical talks and partying all night in Kraków, the Best City in the World (tm). If you're new, congratulations on joining the mayhem and insanity of the Alligator! If you haven't been invited this year but you know us IRL, just ping us and we will add you to the list. If you've only heard of us online and want to join in, send us an email to firstname.lastname@example.org letting us know who you are and why you want to come. Your chances improve dramatically if you also present a talk!
