It’s November 1st! Time to get your NaBloPoMo on.

November is a big month for writers — you’ve probably read about NaNoWriMo, which kicks off today.

Not interested in writing a length book, but looking for a challenge that’ll push you as a blogger? Try NaBloPoMo, National Blog Posting Month, which also starts now: one post a day, however short or long, every day in November. The topic is up to you, as is the format — longform, photo essay, haiku, webcomic, or quick musings; they’re all fair game.

To participate, just start posting! Tag your posts with “NaBloPoMo” to help other bloggers (and us!) find you. You’ve also got until November 5th to add your blog to the official NaBloPoMo blogroll on BlogHer, where you can grab a badge for your blog.

(Why register for the blogroll? One word: community. Oh, and one more: prizes.)

We’ll have more on NaBloPoMo next week, but the clock starts now. Check out our new Blog Event Survival Guide for inspiration, and get posting!
