How It Works:
Follow the links above to the DonorsChoose website.
Pick a project from the slate the blogger has selected (or more than one project, if you just can't choose).
Donate.
(If you're the loyal reader of multiple participating blogs and you don't want to play favorites, you can, of course, donate to multiple challenges!)
DonorsChoose will send you a confirmation email. Hold onto it; our benevolent overlords at Seed will be randomly selecting some donors to receive nifty prizes. Details about the prizes and how to get entered will be posted here soon!
Oh right, and this year, Discovering Biology in a Digital World is offering prizes! Donate over $100, send a copy of your confirmation e-mail to me (digitalbio at gmail dot com) along with your mailing address and I will send you a coffee mug, of your choice, from this collection.
