Update

No one told me about http://www.nanowriye.com/. It predates my groups since it looks like it started in 2002, from what it says on the main page.

According to this calendar at timeanddate.com, we start week 27 tomorrow. Considering I have around 42,152 words so far (though granted, that's out of 800k), I'm not faring too badly. A lot of the narrative and incident overlaps, so that's not too bad.
