My translation:
Open signup has been closed ahead of time and invite mode is on now. Members who rank higher than USER (USER included) have the right to invite others before the 15th of the first lunar month (22nd Feb. GMT+8 of course). 6 invites offered for every member to send. Wish you all the best in the Chinese New Year! (6 is the lucky number in Chinese. "Six" and "Success without a hitch" are homophonic in the language. BTW, the year is 2016.)
