National coordinator Judy White has organized the project by location. Most submissions are from America, but foreign contributions are welcome; Judy is especially trying to build items from Canada and the British Isles.
Contributions can be individual photographs, indexes, and transcriptions. A single page or an entire book can be submitted, as well as links to external sites. Graduation and commencement programs are also welcome items.
One of the highlights of the project is the classified ads. There are people looking for yearbooks and others selling. Maybe you'll get lucky and find a match.
U.S. SCHOOL YEARBOOK DATABASE Ancestry.com has digitized yearbooks into the U.S. School Yearbook database. If you don't have a subscription, try your local library for access. To date, there are more than 1 million names indexed. The collection includes books from middle school, junior high, and high school.
Ancestry.com encourages submissions, so if you are inclined, send a CD with images scanned at no less than 300 dpi. It should include the front and back covers, as well as all interior images. If you are unable to send a CD, contact them for other arrangements.

I've been researching my maternal family tree on ancestry.com (you get two weeks free) and then I uploaded the GEDCOM file to this free hosting service. It's a useful site to host your tree.
