Hello again,
the Saarbrücken hackfest is approaching fast. On Monday, 27th, I will be there at 09:00 o'clock, from then on the doors will be open and everyone is free to come.
The address is Ufergasse 2 66111 Saarbrücken
It's a kind of hidden door between a casino and an adult video store, just step close to it and it will open on its own. There is a lift in the far right corner of the entrance room, or you can take the stairs on the right. The office is in the 2nd floor (German counting, Americans would call it the 3rd floor). The button in the lift says, among others, "2" (duh), "U2 Raum" and "K8 gGmbH". I will add some photos to the wiki page later.
In case someone wants to get into the office on Sunday already, just ping me and I can arrange something.
For those that are in the city on Sunday and don't know what to do, I'd suggest going for a drink in the evening.
Tobias
PS: If anyone needs any help or information regarding the hackfest, traveling in Germany or local customs I am sure I can help.
