https://wiki.debconf.org/wiki/DebConf18/OpenDay 我加了個開幕式（誰主持？），下午亦分 B, C 場， 不然怎麼容納那麼多的 https://wiki.debconf.org/wiki/DebConf18/OpenDay#Unconfirmed.2C_Suggestions 呢？
I added an Opening Ceremony (who will preside?) and split the afternoon sessions into B and C (else how to handle so many potential speakers?) Also are there any confirmed room numbers I can add to the page yet?
