HK ROR user group deserves some long waited actions. I think there’s enough critical mass in Hong Kong now, and there’s definitely a community. The old google group was disappeared without much given reasons, but we’ve formed a new one. http://groups.google.com/group/hkror
Please sign up again and follow the new blog http://rubyonrailshk.com.
Also let me know if you’d like to help organise or contribute as a speaker in upcoming meetup events.
