I found this on WT forums yesterday so I figured I'd let everybody know.

They still have room on the German team I believe.
Since Pand mentioned that we're looking for ideas for the "Event Server", this may help us as well.
I personally would love to attend but at this point I'm not sure about what the wife has planned for this weekend considering that the kids are on vacation from school and this is my only day off this week.
The time for the event is on Sat @ 1pm EST.
