What Danke said.
I'm way too far east for this to attend anyway, but for me, paying that much for an event organised by people I don't know, and for which no one I know and trust can vouch... Dunno. I'm not ready to jump on it with so much unknown.
If I were you, I would have organized something more modest, like a 12-hour OP to get your name out there, to show people that you have the organisational skills, experience and mindset to do it. Put shortly, to build a relationship with the community. I can totally understand everyone's concerns here.
With that said, I still kinda like what I read on the site and I'll be following what happens. Who knows, if the experience is positive maybe there could be such event closer to home.
