The Next One Up Is JaNoWriMo
From The Desk of Liz Ensley:
Janury Novel Writing Month is the next big WriMo coming up. Particulars are on the page. Where it differs from NaNoWriMo is that it allows continuation of previous works. In other words, you can use it to finish your NaNoWriMo. If you want to write over or under 50k, that's also fine, but you're supposed to email one of the administrators for the go-ahead.
