In support of NaNoWriMo, my friend asqmh has created a new community: 1700wordsperday. Yes, there are already several other LJ communities devoted to NaNoWriMo (including nanowrimo, e.g.), but this one is going to be full of people that I know who are participating.
So, if you read my journal and are interested in NaNoWriMo, you might consider joining 1700wordsperday. It' the happening place to be.
