Organizing the 2015 Google I/O Extended in Düsseldorf was a great experience!

As always the Google's Developer Group community was super helpful to set up this event.

The GDG Düsseldorf chapter team added a special contest which ended at the Google I/O called "Summer Fun Challenge".

Many developers and tech enthusiasts from in and around Düsseldorf joined in good spirits, even-though the classic German summer weather tried to sabotage us with a true rain storm. My Respect goes out to all of the people attending and especially to the nine brave teams / participants of this year's Summer Fun Challenge!

The winners were chosen by the 60 guests attending the event. 47 votes were registered through a Google Docs form.

Things I learned during the organization of this event:

• Using Google Hangouts for video conferencing is really fun and feels like we're really in the future now.
• Google Docs forms have a "results summary" view.
• Scrolling in Google Sheets can be optimized. Had some trouble with this during the event.
• People can be super creative and funny at times.
• We have a great team in GDG Düsseldorf.
• Event registrations don't really mean that people will actually attend. We had an attendance rate of 54.13% of RSVP's.

Also big thank you to the team: Ann-Katrin, Frederik, Jens, Randy, Resul and the others who helped set it up.
