This looks like so much fun! I'd love to go, but the timing simply doesn't work for me. 7 PM EST is 1 AM where I live, and I just can't code at 1 AM. I could barely keep my eyes open. A quick note; if you want stuff like this to be as worldwide as possible, try scheduling it earlier in the day in the US. The earlier it is in the US, the more of Europe and Asia you can get. At the time it is right now, it's not really feasible for any of Europe, Africa, or West Asia. I'd suggest mid-morning (EST) on a Saturday for the most worldwide availability. Just try to work with time zones.
I hope you guys have a great time! Wish I could attend, but I'll be coding on my own, never fear.
