Hi Brad,
No, it does not. This was considered a long time ago but in the end I decided not to do this because the range of topics discussed would be too wide to make the group really useful. I think it would be more a distraction than anything, basically. The format for a forum is better as a catch-all for a wide range of subjects, and the content here is searchable so I don’t think it would translate well to WeChat.
However, there are Chengdu WeChat groups for tons of different things: movie fans, game discussion, UFC watchers, chess players, Chinese learners.. and those are just the ones I’m in. If you want an invite to any of those, add me on WeChat and I’ll send you an invite.
