openSUSE Conference 2015

Yes.

We used Geeko money as drink tickets to control the cost of the party. this worked out reasonably well and thus should be repeated. A "free for all" party is not really an option. Each geeko bill represents 1 drink ticket, beer wine or soft drink, no liquor. Based on the price of the drinks at the selected venue a decision can be made about how many drink tickets to hand out at registration.
