UPDATE2 (2015.01.19) VERY IMPORTANT NOTE:
As we have noted here, we use our local registration site to do the actual work -- Please do not register at GGJ jam site location page only! And unfortunately our venue has already been full! I repeat: If you haven't registered at our local registration page yet, do not register at this page!
Our local registration site has just gone online! All the event details are listed there, and I'll also send email to instruct whoever registered on this jam site page to register on our local site. So please check your email regularly! : )
Our reg site: http://kktix.com/events/mitjam4-ggj2015
If you happened not to be a Chinese speaking person, worry not! My email to you will contain some explanation in English and help you walk through the reg page. If you still need further assistance, or I've accidentally overlooked your case, just simply email me! (igdshare [at] igdshare.org)
