2. Ticket sale. AFAIK FUDCon is always free for everyone to attend, both as in "freedom" and "free beer". So "selling" a ticket does not sound quite right to me. I suggest free entrance while accepting donation instead. Besides, you need to ensure the income is fully used to cover logistics, travel expense of FUDCon.
Thanks for your bidding for the next FUDCon in APAC. Your wiki page has quite a lot of useful information! Please continue to improve it. Meanwhile, I have two concerns:
1. Organization team. There are about 350 participants expected. But only two are listed in the team. I'd say you need spend time building a bigger team to serve the crowd.
