Ask your team and your supporters to share their love for the mission online, and they could net your organization part of $400 in prizes while getting everyone in their social networks excited for GAgives on #GivingTuesday.

Here's how it works:

From November 1 - 17, post a photo or video of yourself and a message of support for your favorite organization – what we call an “un-selfie” – to Facebook, Twitter, or Instagram.

Be sure to write your message out in letters large enough to photograph (or you can download our printable #UNselfie template here), and don’t forget to caption it with the hashtags #GAgives, #GivingTuesday, and #UNselfie, so we can find it.

We’ll be sharing #UNselfies on our @GAgives social networks, extending your nonprofit’s message across the community!

Ten finalists will be featured in a Facebook gallery starting Nov. 22 and, for the next five days, our followers (and yours) can vote for their favorite with a “Like.”

We’ll announce the winners on Nov. 27, awarding a donation to the top three: $250 for first place, $100 for second, and $50 for third, provided by GCN.
