Hi,
no, none from my own writing group, but there are many other authors from Fredericton and the region that are doing it. Also, some of the authors I have been in touch with over the years are back, which is fun.
Each locations has representatives, who organize events throughout November, such as in-person writing sessions, or virtual writing sessions. The NaNoWriMo website also have a forum, with a regional section (and a bunch of other discussions, organized by age, genre, locations, etc.). Any way you look at it, NaNoWriMo is good platform to get in touch with other writers in your community, or abroad.
