takeshi - number is hard to answer, because some times member is active or not , long time contributors - people will active or inactive.Community members spread over Japan, some of them live in Nagoya,or Hiroshima, for exapmle, far from Tokyo.
Is it not enough to finish l10n tasks? 10x ~ 20x member we need to complete the translation (MDN) than number of members. we have now.
There is only one Mozilla Rep (Sammy) and another one core contributos in HK. Due to the direction change and minimum of support, they seldom have offline events, and mainly focus on online project (etc. Social Network channel & Website). The main limit is lack of contributors.
Only one main contributor (that's Sammy) and too many works for multiple communities.
What do you need to unblock these things?
Need more resource (money & venue).
Money - lack of chance to participated in global/regional gathering will block the chance to bring more info back to Hong Kong. In previous years Sammy had paid for himself travel other country for the same reason.
Venue - It's getting harder and harder to find venue suitable for meetup, easy access and not cost a lot in HK. Most fastfood store don't like meeting events.
