My understandings but it is still better to check with the organiser ...
I believe that those teams which are eligible will receive the news .... through official way, I just help to spread the news in 悟入棋途 lah ..... it is better to check with the organiser for queries.
My understandings from the write-ups :
法定机构 : HDB, LTA, ..........
各CC : 人协属下单位
北斗队: 注册团体组织
飞鹰队 : not 注册团体组织, but could form under Pasir Ris East C.C. (?!)
私人公司 : should be considered as 注册团体组织
裕华队 :still can form under 裕华 C.C. (?!)
华新网 : ??
是"enquiries" 或" queries"; "query" 含质问意义,语气太重点吧!
