Currently, the most Hanfu-aware group outside of China would have to be CHF - The Chinese History Forums (chinahistoryforum.com). However, like Tianya and Tiexue, there is QUITE a presence of Anti-Hanfu elements in there, including countless Manchus and Manchu supporters.
If you are talking about blogs and translating good essays, then I'm already doing that, with TorGuqin.wordpress.com. There is also a paid-for blog called Hanfu.info, run by Jensen Liu, that attempts to gather NEWS ARTICLES (translated) about the Hanfu movement. If anyone has time to upload news articles (we're out of date since Feb 2009, we need to catch up!), please contact me, and I'll see to adding you as a contributor.
This is of utmost importance. Contact me as soon as possible if you can do it.
