Admission to LinuxNacht costs around EUR 20 (includes a buffet and drinks). If you have in mind to do some networking this would be a good option. There is not an unlimited amount of ticket available for that price. The regular price at the entrance will be EUR 30...I know that there are a lot of list to fill if you are attending LinuxTag but this ways it's easier to handle this kind of stuff. Please sign up at the following wiki page. I hope that Gerold will make then the reservation for the tickets like last year if the deadline is reached. BTW, first comes, first served...Thanks.
