Nope, that’s not a typo. The charity organization Movember has appropriated the month formerly known as November, as they call it, and they want you to do one simple thing: grow a mustache or beard.

Movember encourages guys to grow out their facial hair for an entire month to raise money for men’s health issues. Participants start with a clean-shaven face on November 1, and then grow it out, seeing how far they can get by the 30th. Many groom their moustaches and beards into neat, creative and attention-grabbing shapes and styles to draw more attention to the cause.

So, guys: Are you participating in Movember? Here’s what we want you to do: Upload a photo of your clean-shaven face on November 1, and then send another photo on November 30 so we can see the shocking difference. Be sure to tell us why you’re participating in the fundraiser. You could be part of a story on CNN.com!
